Tips for helping little ones sleep comfortably in hot weather

Hot weather can make it challenging for babies to sleep well. Parents often worry about how to keep their little ones cool and safe during warm nights. Babies are more sensitive to temperature changes, and overheating can increase the risk of sleep problems and even unsafe sleep conditions. This post offers practical advice to help parents prepare for hot weather and ensure their babies sleep comfortably and safely.

Keep the Room Cool and Well-Ventilated

The temperature of the baby’s sleeping environment plays a crucial role in comfort and safety.

• Aim to keep the room temperature between 16°C to 20°C.

• Use a fan or air conditioner to circulate air, but avoid pointing it directly at the baby.

• Open windows for natural ventilation if it is safe and does not expose the baby to drafts. The best times of day are first thing in the morning and late evening.

• Close curtains or blinds during the day to block out heat from sunlight.

  
  

Monitoring the room temperature with a thermometer can help parents adjust conditions as needed.

Hydration and Feeding Considerations

Hot weather increases the risk of dehydration, especially for young babies.

• For breastfed babies, offer feeds more frequently to keep them hydrated. Under 6 month old's do not need additional water. They may feed more throughout the night too.

• Formula-fed babies under 6 months shouldn't need water unless they're showing signs of dehydration, the NHS states to offer small sips of cool boiled water if they are showing signs. Always consult your GP/ pediatrician before adding water.

• Over 6 months can drink tap water in England without it being pre-boiled.

• If weaning or weaned, offer foods in high water content such as, watermelon, cucumber, apple, oranges, tomatoes, and frozen yoghurt, ice lollies, & cold snacks are going to help too.

• Watch for signs of dehydration such as fewer wet nappies, dry mouth, or unusual fussiness.

  
  

Proper hydration helps regulate body temperature and supports restful sleep. Please visit the NHS website for more details on recognising the signs of dehydration and how to manage it, and if concerned call 111.

Stay safe outside in the heat

This applies to all children but especially babies under 6 months old.

• Never cover your pram or buggy with a muslin, blanket, towel, avoid anything that can trap the heat, as this creates a much hotter environment than outside the buggy!

• It is safest to use a parasol & pram hood with mesh inserts to allow air flow.

• Keep out of direct sunlight, avoiding the highest temperatures, between 11 am & 4 pm (although I feel these hours could shift even later!), find shady spots as much as possible.

• Use a sun hat when outside, always apply, and re-apply sunscreen that is child friendly.

• Dress them in lightweight, breathable clothing.

• Make use of water play and offering damp cool flannels throughout the day and evening offers well needed cool time!

• Take the opportunity to have an easier day and slow down, everyone can find the heat unbearable, tiring, and uncomfortable.

Use Safe Sleep Practices in Hot Weather

Maintaining safe sleep is essential regardless of temperature, but hot weather requires extra attention.

• Always place your baby on their back to sleep on a firm mattress.

• Keep the crib/ cot clear: free of pillows, stuffed toys, and loose bedding that could cause overheating or suffocation.

• Avoid using blankets or quilts; instead, a sleep sack made of breathable material (always check the size and tog is right for the temperature) or simply put them in as they are.

• Remember body heat can make a baby hotter, so make sure you are placing them down in a safe environment to allow their bodies to cool down and you can oversee them on a regular basis. You can use a Muslin between your body and theirs to help soak up the moisture in the moments you are holding them, but keep it away from their face area.

• Check your baby regularly for signs of overheating such as sweating, flushed cheeks, or rapid breathing.

• If the room or house is simply too hot and you don't have a fan or air conditioning, take them out of the room and find the coolest room or an air conditioned environment, a cafe or a supermarket in the buggy might help.

  
  

Safe sleep guidelines help reduce risks and keep your baby comfortable.

Monitor Your Baby’s Comfort and Adjust as Needed

Room temperatures are harder to control in extreme hot temperatures, and babies cannot tell you when they are too hot or cold, so parents need to observe and respond to what they can control.

• Feel your baby’s neck or back to check for sweating or clamminess.

• If your baby feels hot, remove a layer of clothing, or do your best to adjust the room temperature.

• If your baby seems cold, add a light layer or adjust the environment accordingly.

• Use a baby-safe thermometer to monitor body temperature if you suspect overheating.

  
  

Being attentive helps prevent discomfort and supports healthy sleep habits.

Create a Comfortable Sleep Routine

A consistent sleep routine helps babies relax and fall asleep more easily, even in warm weather.

• Open windows for ventilation in the evening as the sun goes down, and close them when you go to bed.

• Use calming activities like a lukewarm bath or gentle massage to regulate and reduce high temperatures before sleep.

• Avoid heavy meals or sugary drinks close to bedtime, as they can increase body temperature too.

• Pick your battles! Everyone can feel agitated in the heat, so it isn't worth the fuss at bedtime. Roll with it and know they will get sleep.

  
  

A predictable routine signals to the baby that it is time to wind down, which supports better sleep quality.

It is important to remember that it is normal for sleep to go off course during hotter temperatures, so don't worry if sleep has a wobble, you're doing your best.
