How to Keep Your Kids Healthy and Nourished This Summer - Tips for Parents

Summer break can disrupt routines, but it shouldn't disrupt your child's nutrition.

Without school schedules and structured meal programs, many kids eat fewer fruits and vegetables, skip breakfast, and miss out on essential nutrients. Additionally, 2023 research published in the journal Pediatric Obesity showed that kids are less likely to engage in physical activity and display poor diet behaviors during the summer holidays.

As a parent, you’ll likely want to take proactive steps to keep your children nourished in between school semesters. That’s what we want to help you do!

This guide covers how parents can support kids' nutrition during summer months with practical tips, research-backed guidance, and a spotlight on liquid vitamins for children.

Why Nutrition Matters During Summer

During the school year, many children rely on school lunches that follow USDA dietary guidelines, providing balanced meals with the right mix of fruits, vegetables, proteins, and whole grains. These meals act as a reliable nutritional safety net for families, helping kids receive essential vitamins and minerals every day.

When summer arrives and school is out, that safety net often disappears. Without structured meal programs, it becomes easier for kids to fall into less healthy eating habits.

This isn’t just about weight gain it reflects shifts in eating patterns, reduced physical activity, and, sometimes, nutrient imbalances.

According to this 2019 study, children often experience changes in their physical activity levels and dietary habits during the summer. While some may engage in more outdoor activities, others might face increased sedentary behavior due to factors like screen time.

This shift can lead to weight gain and decreased physical fitness, particularly among underprivileged adolescents.

A healthy diet is crucial all year round, but it becomes especially important during summer when kids are active outdoors, growing quickly, and exposed to new challenges like increased sun exposure and environmental changes. Eating foods rich in vitamin C, vitamin D, folic acid, iron, and other essential nutrients helps support their immune health, supports brain development, fuels healthy growth, and maintains steady energy levels.

Without these nutrients, kids may feel sluggish, be more prone to illness, or struggle with focus and mood. That’s why parents can’t afford to let nutrition take a backseat just because school’s out.

How Nutrition Affects Mood and Behavior in Kids

What children eat doesn’t just impact their physical health; it also plays a big role in how they feel and behave throughout the day.

Nutrient-rich foods help support steady energy levels, focus, and emotional balance, while diets high in sugar and processed foods can lead to mood swings, irritability, and difficulty concentrating.

For example, blood sugar spikes from sugary snacks can cause a quick burst of energy followed by a crash, leaving kids tired and cranky. On the other hand, balanced meals with protein, fiber, and healthy fats provide sustained energy and support brain function. Vitamins like B-complex, vitamin C, vitamin D, and minerals such as iron and zinc are essential for neurotransmitter production, which affects mood regulation and cognitive performance.

When children don’t get enough of these nutrients, they may show signs of restlessness, anxiety, or trouble focusing, making it harder for them to engage in learning or play. For picky eaters or kids with limited diets, liquid vitamins can help fill nutritional gaps that support healthy brain development and emotional well-being.

In short, good nutrition is a foundation not just for physical growth, but for stable moods and positive behavior, something every parent can appreciate during the busy, unstructured days of summer break.

What Are the Most Common Summer Nutrition Challenges?

When school lets out for summer, children often lose the daily structure that supports balanced meals and regular eating habits. Without school breakfasts and lunches, many families face added challenges in providing nutritious meals throughout the day.

As a result, some children may miss meals, snack excessively, or rely on highly processed foods. Below are some of the most common nutrition pitfalls during the summer months and why they matter.

1. Skipping Breakfast

During the school year, breakfast is often built into a child’s morning routine, either at home or through school meal programs. However, in summer, later wake-up times and looser schedules can lead to breakfast being skipped altogether.

Skipping breakfast can affect a child’s energy levels, mood, and focus throughout the day. According to resources from the American Academy of Pediatrics, children who miss breakfast also seem to be more likely to develop metabolic conditions such as high blood sugar.

Breakfast also sets the tone for healthy eating patterns later in the day, helping prevent overeating and cravings for processed snacks.

2. More Junk Food, Less Healthy Food

Without the oversight of school meal programs, many kids turn to what's convenient, such as chips, sugary drinks, and packaged snacks. These foods are typically high in added sugar, sodium, and unhealthy fats while offering very few essential nutrients.

Replacing balanced meals with junk food increases the risk of nutrient deficiencies and can contribute to poor immune health, low energy, and weight gain.

As shared by the Centers for Disease Control, the Dietary Guidelines for Americans recommend limiting added sugars to less than 10% of daily calories for children over 2 years old. In summer, without careful planning, many children exceed that limit before lunchtime.

3. Less Structure and More Snacking

A lack of structure during the summer often leads to more grazing throughout the day. Kids may eat out of boredom or habit rather than hunger, especially when snacks are easy to reach and unsupervised.

Constant snacking, particularly on low-nutrient foods, can reduce appetite for balanced meals and make it harder to track nutritional intake. Offering scheduled meals and healthy snacks like fruit, nuts, and yogurt can help build a better routine and limit empty calories.

4. Inconsistent Mealtimes

Without school bells dictating lunch and snack periods, summer mealtimes can become irregular. One day lunch is at noon, the next it’s at 3:00 p.m. These shifts can confuse a child's hunger and fullness cues.

Inconsistent mealtimes can also impact blood sugar regulation and digestion. A consistent eating schedule supports more predictable hunger patterns and reduces the likelihood of overeating or skipping meals altogether.

5. Reduced Access to School Nutrition Programs

School meal programs play a vital role in many families’ ability to feed their children. When school is out, that support disappears for millions of kids.

This gap can lead to increased food insecurity, especially for low-income households. Parents may struggle to replace two daily meals with healthy, affordable alternatives at home, making nutrient-dense supplements like liquid multivitamins an essential part of supporting a child’s overall health during summer.

Tips to Keep Your Children Healthy This Summer

Supporting your child's nutrition during the summer doesn't have to feel like a chore or an added stress. With the right strategies, families can maintain balanced diets, meet daily vitamin and mineral needs, and promote overall health, even without the structure of the school day.

Below are practical, specific tips for keeping your children nourished, hydrated, and energized

all summer long.

Tip #1: Start With a Healthy Breakfast

As we touched on, skipping breakfast can lead to low energy, poor concentration, and increased cravings later in the day. Conversely, a healthy breakfast jumpstarts metabolism and provides the nutrients kids need to fuel summer activities like swimming, biking, and outdoor play.

Build breakfasts around a balance of protein, fiber, and healthy fats. Some quick, nutritious options include:

  • Whole grain toast with peanut butter and banana slices
  • Scrambled eggs with spinach and cheese wrapped in a whole wheat tortilla
  • Greek yogurt with granola and mixed berries
  • Overnight oats made with milk, chia seeds, and diced apples

Another tip: Avoid sugary cereals or breakfast bars with high fructose corn syrup. They can spike blood sugar and leave kids feeling sluggish soon after eating.

Tip #2: Use Liquid Vitamins for Children to Fill Gaps

Even with healthy meals, most children don’t get all the nutrients they need every day, especially in the summer when routines are more relaxed. This is where liquid vitamins for children can make a difference.

Unlike pills or chewables, liquid multivitamins deliver nutrients in a form that’s easier for the body to absorb. They’re also simple to mix with juice or water, which is helpful for younger kids or picky eaters.

The best liquid vitamins offer a convenient way to support immune health, brain development, and healthy growth, especially when fresh produce or protein-rich meals aren’t always available. They can also help cover shortfalls in nutrients like vitamin D, vitamin C, folic acid, and essential minerals like zinc and magnesium.

Why Choose Liquid Over Gummy Vitamins?

Gummy vitamins may seem like a child-friendly option, but they come with downsides:

  • Many contain added sugar, unhealthy fillers, and artificial flavors
  • Their nutrient levels are often lower than those in liquid multivitamins
  • They can stick to teeth and contribute to cavities if not followed by brushing

In contrast, liquid vitamins are better. They are more likely to contain no added sugar, no gelatin, and offer a broader spectrum of nutrients per dose. Additionally, they’re easier to measure and can be adapted based on a child’s age or dietary needs.

Most importantly, liquid forms support higher absorption rates, which means your child may get more of the vitamins and minerals listed on the label.

What to Look for in a Kids' Multivitamin:

Choosing the right kids' multivitamin is the first step toward excellent summer nutrition. Look for the following features to maximize value and safety:

  • A full range of essential vitamins
  • Important minerals like zinc, magnesium, selenium, calcium, and iodine
  • Clearly labeled dosages based on age or weight
  • No GMOs, artificial dyes, or high-fructose corn syrup
  • A flavor your child enjoys (taste matters for consistency!)

Some products also include added antioxidants, omega-3s, or probiotics, which may support digestive and immune system health.

At Passion 4 Health, our daily liquid multivitamin is formulated to support the nutritional needs of growing kids without compromising on purity, taste, or bioavailability. It’s designed for the whole family, from your youngest member to the oldest!

Tip #3: Make Healthy Eating Easy and Fun

Kids are more likely to eat healthy foods when they’re involved in the process. Let them help wash fruits, arrange veggie snack plates, or build their own sandwich using choices from each food group.

Another idea: you can try this simple formula for lunch or dinner…

  • A protein (turkey, hard-boiled eggs, beans, or tofu)
  • A vegetable (carrot sticks, cucumbers, cherry tomatoes)
  • A fruit (orange slices, grapes, berries)
  • A whole grain (brown rice, whole wheat wrap, or quinoa)
  • A dairy or non-dairy alternative (milk, yogurt, or cheese)

You can also make snack time healthier with options like frozen fruit pops made from 100% juice, smoothies with added spinach, or homemade trail mix.

Tip #4: Keep Hydration Front and Center

Water is often overlooked, but it plays a major role in digestion, temperature regulation, and energy. During the hot summer months, children are more susceptible to dehydration, especially if they’re active outdoors.

Encourage your child to drink water throughout the day. A good rule of thumb: kids ages 4–8 need about 5 cups per day, while older children may need 7–8 cups depending on their activity level (per Harvard Health).

To make hydration more appealing, try:

  • Adding fresh fruit or mint to water for flavor
  • Letting kids choose a fun water bottle with measurement marks
  • Offering snacks with high water content, like watermelon or cucumbers

Another tip: Skip the sugary drinks, as they can contribute to blood sugar spikes and poor overall health.

Tip #5: Support Nutrition with Physical Activity

Nutrition and physical activity go hand in hand. Exercise helps regulate appetite, strengthens muscles and bones, and supports emotional well-being.

That’s why the CDC recommends that kids get at least 60 minutes of moderate to vigorous physical activity each day. During summer break, that might include:

  • Riding bikes around the neighborhood
  • Swimming at a local pool
  • Playing soccer, tag, or capture the flag
  • Dancing, jump rope, or active video games indoors on hot days

Pairing a healthy diet with physical movement helps your child absorb nutrients more effectively and encourages healthy habits that last beyond summer.

Tip #6: Help Picky Eaters Expand Their Palates

If your child is a picky eater, you're not alone. Many parents struggle to offer variety without mealtime battles.

Patience and consistency go a long way. Here are some strategies that may help:

  • Serve small portions of new foods alongside familiar favorites
  • Avoid pressure, just offer and re-offer (it may take 10–15 exposures!)
  • Let your child help with shopping or simple meal prep
  • Make food fun: use cookie cutters to shape sandwiches or fruits

While your child learns to accept more flavors and textures, liquid vitamins can act as nutritional insurance. A high-quality kids' multivitamin provides daily essential nutrients even on days when meals are less balanced.

For many picky eaters, a liquid multivitamin is easier to take than chewables or gummies, especially if it can be added to a favorite drink.

What Nutrients Do Kids Need Most in Summer?

Certain vitamins and minerals are especially helpful for supporting your child's immune health, growth, and energy during this active season. Making sure your child gets these nutrients (through food or a quality liquid multivitamin) can help support their overall health.

Summer Nutrition Essentials for Kids: A Quick Guide

Nutrient Benefits Food Sources Signs of Deficiency Supplementation
Vitamin D Supports bone health, immune function, and muscle health. Sunlight, fortified milk, fatty fish, and egg yolks Fatigue, frequent infections, delayed growth, and bone pain. Vitamin D3 with Vitamin K2 supports calcium absorption and bone growth.
Vitamin C Boosts the immune system, helps with skin health, aids iron absorption. Citrus fruits, strawberries, bell peppers, broccoli Fatigue, irritability, slower wound healing, and bleeding gums. Liquid Vitamin C supplements support immune health, especially for picky eaters.
Zinc Supports immune function, wound healing, and growth. Meat, seafood, beans, nuts, seeds Frequent infections, delayed wound healing, and loss of appetite. Liquid Zinc supplements are easier for kids to take and provide accurate dosing.
Omega-3s Important for brain development, heart health, and reducing inflammation. Fatty fish (salmon, mackerel), walnuts, flaxseeds Difficulty concentrating, mood swings, dry skin, and poor cognitive function. Liquid Omega-3 supplements can provide the necessary fatty acids, often flavored for easier consumption.
Magnesium Supports muscle and nerve function, energy production, and bone health. Nuts, seeds, whole grains, leafy greens, legumes Muscle cramps, fatigue, irritability, trouble sleeping, and restless leg syndrome. Magnesium in liquid form is easily absorbed and ideal for active children who may have higher magnesium needs.

Here is a detailed breakdown of the essential nutrients your child needs for optimal health this summer:

1. Vitamin D

Vitamin D plays a significant role in helping children build strong bones by aiding calcium absorption. It also supports a healthy immune system, which is extra important during summer when kids are often exposed to new environments and germs.

Moreover, vitamin D contributes to muscle function and brain health, making it essential for active, growing children.

Where does it come from?:

The primary source of vitamin D is sunlight—when skin is exposed to UVB rays, the body synthesizes this nutrient naturally. However, many kids don’t get enough sun exposure due to sunscreen use, indoor activities, or living in less sunny regions. Dietary sources include fortified milk, fatty fish like salmon, egg yolks, and some fortified cereals.

Signs your child may be deficient:

Children with low vitamin D levels may experience fatigue, frequent infections, or delayed growth. In more severe cases, deficiency can lead to bone pain or softening (rickets).

If your child shows signs of muscle weakness, irritability, or frequent colds, it might be worth discussing vitamin D levels with your pediatrician.

How to supplement:

Supplementing with vitamin D3 combined with vitamin K2 is typically considered the best option for children.

Vitamin D3 is the natural, most bioavailable form of vitamin D that the body uses most efficiently. Vitamin K2 works synergistically with vitamin D3 by helping direct calcium to the bones where it’s needed, and away from soft tissues and arteries. This combination supports healthy bone growth and overall cardiovascular health.

2. Vitamin C

Vitamin C is well-known for its role in supporting the immune system, helping the body fight infections and recover faster from illnesses. It also aids in skin health by promoting collagen production, which is important for healing cuts or sun-exposed skin.

Additionally, vitamin C improves iron absorption, which supports energy levels and cognitive function.

Where does it come from?:

Fresh fruits and vegetables are rich sources of vitamin C. Citrus fruits (oranges, grapefruits), strawberries, kiwi, bell peppers, and broccoli are especially high in this nutrient. Because vitamin C is water-soluble and sensitive to heat, fresh or lightly cooked produce is best.

Signs your child may be deficient:

A vitamin C deficiency can cause fatigue, irritability, and slower wound healing. In rare cases, severe deficiency leads to scurvy, which includes symptoms like bleeding gums, joint pain, and bruising.

If your child often seems run down or takes a long time to recover from minor cuts and scrapes, vitamin C levels might be worth checking.

How to supplement:

For kids who are picky eaters or don’t get enough fruits and veggies daily, a liquid vitamin C supplement can help bridge the gap. Liquid forms are gentle on the stomach, easily absorbed, and can be mixed with juice or water for an easy-to-take option that supports immune health all summer long.

3. Zinc

Zinc is a mineral that supports immune function, helps wounds heal faster, and plays a role in growth and development. It also contributes to proper taste and smell, which can influence appetite and food choices in children.

Where does it come from?:

Zinc is found naturally in meat, seafood, legumes (like beans and lentils), nuts, and seeds. While many children consume enough zinc through diet, picky eaters or those on vegetarian diets may be at risk of lower intake.

Signs your child may be deficient:

Zinc deficiency can cause frequent infections, delayed wound healing, loss of appetite, and growth delays. Some children may also experience hair thinning or changes in taste sensation. If your child seems unusually prone to colds or has slow-healing cuts, their zinc intake should likely be evaluated.

How to supplement:

Supplementing with a liquid zinc vitamin can be particularly helpful during summer when children are more physically active and prone to minor injuries or illnesses. Liquid zinc supplements allow for accurate dosing and are easier for kids to take than pills, especially if combined with other essential nutrients in a multivitamin.

4. Omega-3s

Omega-3 fatty acids are essential for brain development, cognitive function, and heart health. They also have anti-inflammatory properties that may support overall wellness and help maintain healthy skin, which is important during summer months spent outdoors.

Where does it come from?:

The best sources of omega-3s are fatty fish such as salmon, mackerel, and sardines. Plant-based sources include walnuts, flaxseeds, and chia seeds, though these provide a form of omega-3 that the body converts less efficiently.

Signs your child may be deficient:

Signs of omega-3 deficiency can include difficulties with concentration, mood swings, dry or flaky skin, and delayed cognitive development. Children who show challenges with focus or learning may benefit from a check to confirm there are enough omega-3s in their diet or through supplementation.

How to supplement:

Many children do not consume enough omega-3s through diet alone. Liquid omega-3 supplements made specifically for kids are a practical way to fill this gap. They often come flavored to mask fishy tastes and provide a pure, easy-to-digest source of these essential fats, supporting brain function and healthy growth through the summer and beyond.

5. Magnesium

Magnesium is a vital mineral that supports many functions in the body, including muscle and nerve function, energy production, and bone health. It helps regulate muscle contractions and relaxation, making it important for active kids, especially during summer when they may be more physically active.

Where does it come from?:

Magnesium is naturally found in foods like nuts (almonds, cashews), seeds (pumpkin, sunflower), whole grains (brown rice, oats), leafy green vegetables (spinach, kale), and legumes (black beans, lentils). Many children may not get enough through diet alone, especially if they favor processed foods over whole foods.

Signs your child may be deficient:

A magnesium deficiency can show up as muscle cramps, fatigue, irritability, or difficulty sleeping. In some cases, kids may experience restless leg syndrome or increased sensitivity to noise and light.

If your child is often tired or complains about muscle discomfort, it may be worth discussing magnesium intake with your pediatrician.

How to supplement:

Supplementing with magnesium through a liquid multivitamin or a dedicated liquid magnesium supplement is an effective way to support daily needs. Liquid forms tend to absorb well and are easier for children to take than pills.

Always follow dosing instructions carefully and consult your pediatrician before starting supplements, especially if your child takes other medications.

Frequently Asked Questions

1. How do I know if my child is getting enough vitamins from food alone?

It can be challenging to know for sure if your child is getting all the vitamins they need just from their diet. A well-rounded diet that includes a variety of healthy foods, fruits, vegetables, whole grains, lean proteins, and dairy usually provides most of the necessary nutrients. However, picky eating, irregular meal patterns, and limited food choices can make it difficult for some kids to get enough essential vitamins and minerals.

If your child frequently feels tired, gets sick often, has trouble concentrating, or shows slow growth, these may be signs of nutrient gaps. Consult your pediatrician to determine if your child’s diet meets their nutritional needs or if adding a liquid multivitamin could be beneficial to support their health during summer and beyond.

2. At what age can kids start taking liquid vitamins?

Most children can start taking liquid vitamins around one year of age, but it’s always a good idea to check with your pediatrician first, especially if your child has specific health needs or is taking other supplements.

Generally, liquid vitamins are easier for young children to swallow and absorb, making them a great option as your child transitions from breastmilk or formula to solid foods.

3. Can liquid vitamins replace food for picky children?

Liquid vitamins are a helpful way to fill in the gaps, but they are not a substitute for food. Whole foods provide a wide range of nutrients (like fiber, healthy fats, and plant compounds) that supplements can’t fully replicate.

That said, for picky eaters who regularly skip vegetables, dairy, or proteins, a high-quality liquid multivitamin can offer peace of mind. It ensures they’re still getting essential nutrients while you continue to introduce a wider variety of foods.

4. What if my child refuses to take vitamins?

If your child resists taking vitamins, don’t worry, this is common! Many parents find success by mixing liquid vitamins into a small amount of juice, applesauce, or a smoothie. You can also use a small oral syringe to make dosing easier for toddlers. Taste plays a big role, so choose a brand known for being kid-approved.

5. Are gummy vitamins bad for children?

Gummy vitamins are popular, but they come with drawbacks. Many contain added sugars, artificial flavors, unhealthy fillers, or food dyes. They can also stick to teeth and contribute to cavities if kids don’t brush soon after taking them.

While gummies may be better than nothing, liquid multivitamins usually provide a more complete blend of essential vitamins and minerals, without the extra sugar or sticky texture. They can also be easier to dose accurately, especially for younger kids.

6. What’s the best time of day to give liquid vitamins?

The best time to give liquid vitamins is with a meal, usually breakfast or lunch. Taking vitamins with food can help improve absorption and prevent stomach upset, especially for nutrients like vitamin D, vitamin E, and iron that are better absorbed with dietary fat.

Choose a time that works with your family’s routine and stick to it daily so it becomes part of your child’s summer health rhythm.
