We’re used to bundling up in Britain, but when a heatwave hits, staying cool becomes the real challenge, especially for our little ones. Overheating can affect sleep, and more importantly, it can pose a risk to your little one’s safety.
So, how do you help your child sleep soundly when the temperature soars? Here are practical and safe tips to help your baby stay cool through the night.
1. Monitor the room temperature
Keeping your child’s sleep space at a safe temperature is essential. The Lullaby Trust recommends a room temperature of 16-20°C. Using a room thermometer takes the guesswork out, especially during hot spells.
At night, the best way to check if your baby is too hot or too cold is by feeling the back of their neck or chest. Hands and feet often feel cooler, so they’re not the best indicators.
2. Dress for the weather
Think simple. If it’s warm, a lightweight cotton vest – or even just a nappy – might be enough. You could also consider a 1 or 1.5tog Grobah, which are suitable for rooms between 20-24°C. Ask yourself, “Would I be comfortable sleeping in this?” Babies often sleep better when they’re dressed appropriately for the temperature. Also, watch for temperature dips in the early hours, as a cooler breeze may mean your baby wakes up chilly.
3. Keep the nursery cool
To prevent the bedroom from overheating:
- Close curtains or blinds during the day to block direct sunlight.
- Open windows when it’s cooler outside to allow fresh air to circulate.
- Use a fan in a safe position, ideally with a bowl of ice water in front to circulate cooler air. Make sure it’s well out of reach and avoid any trip hazards from wires.
- Try hanging damp sheets or towels in the room, but ensure they’re secure and unreachable by curious little hands.
4. Cool down at bedtime
A lukewarm bath before bed (not cold!) can help lower your little one’s body temperature and ease them into sleep. You can also offer a cool drink of water (if age-appropriate) and gently wipe their forehead or feet with a damp cloth if they seem overheated.
5. Watch out in pushchairs and car seats
When you’re out and about, avoid covering prams or car seats with blankets, even thin ones. It can cause the temperature inside to rise rapidly. Use sunshades or a SnoozeShade designed for airflow and keep checking your little one for signs of overheating.
