Best Drinks for Sleep in Kids

Partly: for children old enough to have them, plain water and age-appropriate plain milk can fit a bedtime routine because they avoid sleep-disrupting caffeine, not because either is proven to make children sleep.

The choice depends on the child’s age, feeding needs and health. For a broader overview, see the guide to the best drinks for sleep.

Which drinks are best for sleep in kids?

The best evening drink is one that meets a child’s usual hydration or feeding needs without caffeine or an untested sleep ingredient. There is no established evidence that a particular drink reliably makes children fall asleep.

Drink	When it is appropriate	Bedtime consideration
Plain water	Small amounts can be introduced at about 6 months; it is a regular drink for older children.	Offer it if the child is thirsty. There is no need to insist on a bedtime drink.
Plain milk	Cow’s milk can be offered as a main drink from 12 months.	Offer it before toothbrushing rather than in a bottle in bed.
Breast milk or infant formula	These are the usual milk feeds for infants during the first year.	Follow the baby’s feeding plan; do not dilute formula to provide extra water.

A drink may be one familiar part of a quiet routine, but that is different from a proven sleep effect. A child who is comfortable and not thirsty does not need a drink simply because it is bedtime.

If sleep is regularly disrupted, consider the whole pattern and speak with the child’s clinician rather than trying to solve it with a new beverage. A drink cannot replace an assessment of persistent sleep problems.

Why might these drinks be safe or unsafe?

Plain water

For an older child, plain water is a straightforward choice when thirst is getting in the way of settling. It contains no caffeine or sugar, and drinking enough across the day supports normal hydration.

Water is not a sedative, and more is not necessarily better at bedtime. A large drink just before sleep may mean the child needs to get up to urinate during the night. Offer water in response to thirst rather than asking the child to finish a set amount.

Plain milk

Plain milk provides fluid and can be part of an age-appropriate diet. Some families serve it during a calming routine, but there is no established evidence that drinking it at bedtime makes children fall asleep.

Milk contains natural sugar, so frequent or prolonged contact with teeth can contribute to cavities. Give it before brushing, and do not put a child to bed with a bottle of milk. Milk is unsuitable for a child with a milk allergy; ask their clinician about an appropriate alternative.

Breast milk and infant formula

For babies, feeds are a source of nutrition and comfort, not a sleep remedy. Night waking and feeding needs differ among infants. Follow the baby’s feeding plan, particularly if there are concerns about growth or feeding.

Prepare formula according to its instructions. Adding extra water can make it unsafe and reduce the nutrition the baby receives. Do not prop a bottle or leave a baby alone with one; place the baby on their back in their own safe sleep space when it is time to sleep.

Caffeine and sweet drinks

Coffee, energy drinks, cola and caffeinated tea can make it harder to sleep and are not good bedtime choices for children. Check labels: a product marketed for relaxation may still contain caffeine or other stimulants.

Juice and sweetened drinks are not established sleep aids. Sugar can contribute to cavities, while acidic drinks can erode tooth enamel. Frequent sipping, especially near bedtime, can increase contact between these drinks and teeth.

Herbal and sleep-promoting drinks

Chamomile, valerian and other herbal drinks are often marketed for relaxation, but their effectiveness and safe doses for children are not established. Ingredients and strength can vary, and some products may cause allergic reactions or interact with medicines.

Do not give a child a melatonin drink or another supplement marketed for sleep without discussing it with their clinician. Keep such products out of children’s reach: a drink-like product may be mistaken for an ordinary beverage. A label describing an ingredient as natural does not establish that it is safe or effective for a child.

How much should a child drink?

There is no recommended amount of any drink specifically for making a child sleep. The goal is appropriate hydration and feeding over the whole day, not a large drink at bedtime. A child who is not thirsty does not need to finish a drink as part of a sleep routine.

Babies younger than 6 months

Breast milk or properly prepared infant formula usually supplies the fluid a baby needs. Do not routinely offer plain water at this age unless the baby’s clinician recommends it. Extra water can replace needed nutrition and may be unsafe.

If a baby seems unwell or feeding is difficult, seek medical advice rather than adding water or changing how formula is mixed. Babies with a specific medical or feeding plan may need individual guidance.

Babies from about 6 months to their first birthday

Small amounts of plain water can be introduced when a baby starts solid foods. Breast milk or formula remains an important source of nutrition and fluid during the first year; water should not replace those feeds.

The water offered during the day is not a bedtime target or a sleep treatment. A baby who was born prematurely, has a medical condition or has a specific feeding plan may need different advice from their clinician.

Children age 1 and older

Water and age-appropriate plain milk can contribute to a child’s usual daily fluid intake. Needs vary with age, activity, weather and health, so there is no single bedtime amount to aim for.

For a child who is thirsty near bedtime, offer some plain water without pressuring them to drink. If nighttime bathroom trips are disruptive, focus on regular drinks during the day rather than giving a large drink just before bed. Do not restrict prescribed fluids to manage sleep.

Keeping the routine tooth-friendly

If offering plain milk, give it before the child’s final toothbrushing. Water is the better choice for an older child who needs a drink after brushing. Avoid putting a child to bed with a bottle.

An infant may still need night feeds. Do not change a baby’s feeding schedule to manage sleep or tooth care without discussing concerns with their clinician.

When should you talk to your child’s doctor?

Ask a clinician for advice if a child regularly has trouble falling asleep, wakes often, snores loudly or seems unusually sleepy during the day. Mention any pauses in breathing during sleep. These problems can have several causes, and a drink is not a substitute for an assessment.

Check before changing drinks or fluid amounts if your child has kidney or heart disease, diabetes, a milk allergy, feeding or swallowing difficulties, or takes medicine that affects fluid balance or sleep. Also ask about any herbal product or sleep supplement before giving it to a child.

Frequent or excessive thirst, especially with frequent urination or weight loss, deserves prompt medical attention. Seek urgent care if these symptoms occur with vomiting, abdominal pain or rapid breathing.

For infants, contact their clinician promptly if feeding is difficult, wet diapers decrease, or you are unsure whether water or formula preparation is appropriate. If a child has trouble breathing, turns blue or is difficult to wake, seek emergency help immediately. If a child may have consumed a sleep supplement accidentally, contact a poison center promptly; seek emergency help for severe symptoms.
