Busy Kids: How to Support Kids’ Energy Without Sugar

Between school, kindy, sports, swimming lessons, playdates and family life, Kiwi kids can have very full days. It is no surprise that many children hit an energy slump by mid-afternoon. For parents, the quick solution can be reaching for a sweet snack, juice box or treat to help them “perk up”.

But while sugar may give kids a quick burst of energy, it often does not last. A better approach is to support steady energy through balanced food, hydration, good sleep, outdoor play and the right daily nutrients.

Here are practical ways New Zealand parents can help support kids’ energy without relying on sugar.

Why Do Kids Get Energy Slumps?

Children use a lot of energy as they grow, learn and play. Their bodies and brains are constantly working, even when they are sitting still in the classroom. Energy dips can happen for many everyday reasons. Children may feel tired if they have not eaten enough at breakfast or lunch, go too long between meals and snacks, or have not had enough water throughout the day. Poor sleep, late nights, big days of physical activity, picky eating, or a limited variety of foods can also contribute to lower energy levels.

Sometimes, tiredness is simply part of a busy day. But building healthy routines can help children feel more settled, focused and ready for what comes next.

Start With a Balanced Breakfast

A sugary cereal or white toast may be quick, but it might not keep kids satisfied for long. A balanced breakfast with protein, fibre and healthy fats can help support steady energy through the morning.

Easy breakfast ideas include eggs on wholegrain toast, Greek yoghurt with fruit, porridge with banana, or a smoothie made with milk, yoghurt and berries. Peanut butter or almond butter on wholegrain toast can also be a filling option (where suitable for your child’s dietary needs). For fussy eaters, keep it simple. Even small improvements to breakfast can make a difference to the day ahead.

Choose Snacks That Last Longer

After school is often when kids are tired, hungry and looking for something sweet. Instead of reaching straight for biscuits or lollies, aim for snacks that combine protein, fibre and slow-release carbohydrates.

Try snacks that combine protein, fibre and slow-release carbohydrates, such as cheese with wholegrain crackers, apple slices with nut butter where appropriate, hummus with carrot sticks, yoghurt with fruit, a boiled egg, homemade oat bars with reduced added sugar, or wholegrain toast with avocado. These options help keep little bodies fuelled without the quick spike and crash that can come from high-sugar foods.

Do Not Forget Hydration

Sometimes, low energy can be linked to not drinking enough water. Young children may not always notice when they are thirsty, especially when they are busy playing. Encourage regular water breaks throughout the day. Sending a named water bottle to school or kindy can help build the habit. For children who resist plain water, try adding slices of orange, cucumber or berries for natural flavour.

Support Energy Through Key Nutrients

A varied diet is the best foundation for children’s health. However, some children may have limited food preferences, smaller appetites or busy routines that make balanced nutrition harder to achieve every day. Nutrients that support normal energy production and overall well-being include:

B vitamins – help the body convert food into energy.
Iron – supports normal energy levels and development.
Vitamin D – supports bones, muscles and immune system function.
Magnesium – supports muscle function and general wellbeing.
Omega-3 DHA – supports brain and eye health.

For children who may need extra nutritional support, a high-quality children’s supplement can help complement a balanced diet. ChildLife NZ offers a range of children’s vitamins and supplements designed to support growing bodies, active lifestyles and everyday wellbeing.

Build Better Sleep Habits

No snack or supplement can replace sleep. Children need regular rest to recharge their bodies and minds. A calming evening routine can help kids wind down after busy days. Try setting consistent bedtimes, limiting screens before bed, reading together and keeping bedrooms calm and comfortable. When children sleep well, they are often better able to manage energy, mood and concentration the next day.

Encourage Outdoor Play

Active play may sound like it uses energy, but it also supports healthy sleep, appetite and mood. Kiwi families are lucky to have parks, beaches, playgrounds and backyards that make outdoor movement part of everyday life. Even a short walk, bike ride or play outside after school can help children reset after a structured day.

Consider ChildLife Essentials supplements

For children who may need extra nutritional support alongside a balanced diet, ChildLife Multi Vitamin & Mineral and ChildLife Liquid Iron may be suitable options to consider:

• Multi-Vitamin & Mineral helps support daily nutritional needs, particularly for children with limited food variety or picky eating habits.

• Liquid Iron supports healthy red blood cell formation and oxygen transport, which are important for active, growing children.

***Always read the label and use as directed. Supplements are not a substitute for a balanced diet. If you have concerns about your child’s health, talk to your healthcare professional.
