When little ones struggle to fall asleep or wake up frequently during the night, we often blame screens, noisy environments, or bedtime routines. But their diet, and the timing of meals, can also play a surprisingly big role in how well they sleep.
Lisa Artis from The Sleep Charity explains how food choices can influence sleep quality, and which foods can be helpful or disruptive.
Why food plays a part in sleep
For children to sleep well, their bodies need the right nutrients to make sleep-supporting hormones. Melatonin signals that it’s time to rest, while serotonin helps create a sense of calm. Both are influenced by what they eat.
If a child’s diet is low in nutrients like magnesium, vitamin B6, and tryptophan, they may find it harder to settle. Likewise, sugary snacks can lead to energy spikes and crashes that disrupt sleep. Eating a heavy meal too close to bedtime can also keep their body busy digesting instead of winding down.
Foods that may encourage better sleep
Some foods naturally help the body relax, making it easier to drift into deeper rest. Adding these to your child’s evening routine may make a difference.
Artis explains: “It’s not about cutting out favourite foods altogether — it’s about being mindful of when you eat them if you want to give yourself the best chance of feeling refreshed in the morning.”
Here are a few sleep-friendly options:
- Oats – A warm bowl of plain oats can be soothing and provides melatonin along with slow-release carbohydrates to help the body settle.
- Bananas – Packed with magnesium, potassium, and vitamin B6, bananas help relax muscles and aid the body in making serotonin.
- Almonds – A source of magnesium and healthy fats, almonds can help support steady blood sugar levels overnight. Offer only if age-appropriate and safe from allergies.
- Kiwi – Rich in antioxidants and serotonin, kiwi has been linked to falling asleep faster and sleeping for longer, and is naturally low in sugar.
Foods to limit in the evening
Some foods can interfere with sleep by causing discomfort or stimulating the nervous system. Artis notes: “Certain foods can place extra strain on digestion, making it harder to stay asleep. If you find that tummy troubles are waking your child, it may help to reduce these foods in the evening.”
Avoid serving these close to bedtime:
- Caffeine – Found in fizzy drinks, energy drinks, tea, coffee, and chocolate. Caffeine blocks adenosine, a chemical that helps you feel sleepy, and can linger in the body for hours. Stop it after lunchtime.
- Spicy meals – These can raise body temperature and trigger heartburn or indigestion, especially late at night. Offer spicy foods earlier in the day instead.
- Heavy, fatty meals – Large portions or rich foods in the evening keep the digestive system working when it should be slowing down. Aim for dinner at least 2–3 hours before bed.
Timing is just as important
Sleep isn’t only about what goes on the plate; when your child eats also matters. Eating right before bed can cause digestive discomfort, but going to bed hungry can be just as disruptive.
Try:
- Keeping meal times consistent during the day.
- Serving dinner a few hours before bedtime.
- Offering a light, healthy snack, like a banana, a small portion of oats, or a few almonds, if they’re peckish later.
Helping children sleep better doesn’t always a new hybrid mattress or blackout blinds. Sometimes, small tweaks to their diet and meal timing can help their body relax, drift off faster, and enjoy more restful sleep.
It may not be a cure-all for every bedtime struggle, but if sleep has become a nightly challenge, adjusting what and when your child eats could be a simple place to start.
