When temperatures soar, getting a good night's sleep can become a challenge for the whole family especially little ones. Babies are more sensitive to heat than adults because they can't regulate their body temperature as effectively, making them more susceptible to overheating during warmer weather.
The good news is that with a few simple adjustments, you can help create a cooler, more comfortable sleep environment that supports safer, more restful nights. From choosing breathable sleep essentials to dressing your baby appropriately for the temperature, here are our top tips for helping your little one sleep comfortably during a heatwave.
Why do babies find hot weather harder?
Babies aren't yet able to regulate their body temperature as efficiently as adults. They can become too warm much more quickly, particularly when they're sleeping, as they can't kick off blankets or adjust their clothing independently.
That's why it's important to pay close attention to your baby's sleep environment during periods of hot weather and make small changes to help them stay comfortable.
How can you tell if your baby is too hot?
It's normal for your baby's hands and feet to feel cooler than the rest of their body, so instead, check the back of their neck or chest. Signs your baby may be too warm include:
- A hot chest or neck
- Damp or sweaty hair
- Flushed cheeks
- Restlessness or difficulty settling
- Faster breathing than usual
If your baby feels hot, remove a layer of clothing and help cool the room where possible.
8 ways to help your baby sleep during a heatwave
1. Keep the bedroom as cool as possible
A cooler bedroom can make a significant difference to your baby's comfort.
During the day, keep curtains or blinds closed to block direct sunlight, particularly in south-facing rooms. As temperatures begin to drop in the evening, open windows to allow cooler air to circulate safely.
If you use a fan, position it away from your baby's cot or crib so air circulates around the room rather than blowing directly onto them.
2. Dress your baby in lightweight, breathable clothing
Less is often more when temperatures rise.
Choose lightweight cotton sleep bag or a short-sleeved bodysuit depending on the room temperature. Natural fibres such as cotton are breathable and help wick away moisture, keeping your baby more comfortable overnight.
Avoid synthetic fabrics that can trap heat.
3. Choose breathable sleep spaces
Where your baby sleeps can also influence how comfortable they feel.
The Tutti Bambini CoZee Air Bedside Crib features breathable mesh sides that encourage airflow while allowing you to keep your little one close during those frequent summer night feeds. Improved ventilation can help maintain a fresher sleep environment while also giving parents better visibility throughout the night.
For older babies moving into their own room, pairing a well-ventilated cot with a breathable mattress and natural cotton bedding helps create a comfortable place to sleep all year round.
4. Use lightweight bedding
Babies don't need heavy blankets during hot weather.
A fitted cotton sheet may be all that's needed on particularly warm nights. If you use a baby sleeping bag, always choose one that's appropriate for the room temperature and check the tog rating carefully before bedtime.
Lightweight bedding allows excess heat to escape more easily while still keeping your baby comfortable.
For the latest safer sleep advice during hot weather, The Lullaby Trust recommends using lighter bedding and checking your baby's temperature regularly.
5. Keep bedtime routines calm
Heat can leave babies feeling overtired and unsettled.
A consistent bedtime routine helps signal that it's time for sleep, even if it's warmer than usual. A lukewarm bath, a story, cuddles and a calm, dimly lit room can all help your little one wind down.
Avoid overly active play just before bedtime, as this can raise body temperature further.
6. Offer feeds regularly
Warm weather can leave babies thirstier than usual.
If you're breastfeeding, your baby may naturally want to feed more frequently during hot weather. Formula-fed babies may also ask for feeds more often. Responsive feeding can help keep your little one comfortable and hydrated.
If you have any concerns about hydration or feeding during periods of extreme heat, speak to your midwife, health visitor or GP.
7. Monitor the room temperature
A nursery thermometer can help you understand how warm your baby's room becomes throughout the day and overnight.
Rather than relying on how the room feels to you, monitoring the temperature makes it easier to decide whether your baby needs an extra layer or one less before bed.
According to the NHS, babies sleep most comfortably in a room between 16–20°C.
8. Keep checking your baby overnight
During particularly hot nights, it's perfectly normal to check your baby's temperature more frequently.
Feel the back of their neck or chest rather than their hands or feet, and adjust clothing if needed. Small changes can make a big difference to their comfort.

- Always place your baby on their back to sleep.
- Keep cots clear of pillows, duvets and loose bedding.
- Avoid hats indoors while sleeping.
- Dress your baby according to the room temperature rather than the weather outside.
- Check your baby's temperature regularly using their chest or the back of their neck.
