When the weather starts getting warmer, it’s important to keep your baby happy, comfortable, and cool. Babies can’t regulate their body temperature as well as adults, which puts them at higher risk for overheating. Luckily, we have put together a few simple steps that can make a big difference.

Here are 7 easy ways to keep your baby cool in hot weather 👇

1. Go for Lightweight Layers

Choose loose-fitting, breathable clothing made from cotton or bamboo. A short-sleeved vest or onesie is often enough. Avoid overdressing — if you’re warm, your baby probably is too.

2. Keep the Room Cool

Use a fan to circulate air or open windows to create a breeze. If you’re using a fan in your baby’s room, place it out of direct reach and angle it so it doesn’t blow directly on them.

3. Offer Extra Feeds

Babies lose more fluids in hot weather, so offer breastfeeds or formula more often to help keep them hydrated. For older babies, offer small amounts of cooled boiled water if needed (check with your health visitor).

4. Avoid the Midday Heat

Try to stay indoors or in shaded areas during the hottest part of the day (usually 11am–3pm). If you’re out and about, use a pram sunshade with ventilation — never drape a blanket over the pram.

5. Use a Baby-Safe Suncream

Once your baby is over 6 months old, you can use a gentle, fragrance-free baby suncream with at least SPF 30 (preferable SPF 50). Under 6 months? Keep them fully shaded instead.

6. Cool Baths and flannels

Give your baby a lukewarm bath or gently wipe their skin with a damp, cool cloth. It’s a quick way to lower their body temperature and refresh them before naps or bedtime.

7. Keep Sleep Spaces cool

Remove thick bedding, bumpers, and cuddly toys from the cot. Dress your baby in a lightweight sleep sack or just a nappy and vest for bedtime. A room temperature of 16–20°C is ideal. If you can get a room thermometer this is a great way to monitor how warm your rooms are getting.

How do I know if my baby is too hot?

Check the back of their neck or chest — if it feels sweaty or hot, they may be overheating. Fussiness, flushed skin, and rapid breathing can also be signs.

Final tip: Babies under 6 months should be kept out of direct sunlight. A wide-brimmed hat and shade are your best friends in summer ☀️
