How to Keep Your Baby Cool and Comfortable in Hot Weather - Summer Sleep Tips

When the sun is shining and the days are long, it’s lovely to enjoy the outdoors with your little one – but warm weather can also bring questions about how to keep your baby cool, especially at night. Babies can’t regulate their temperature as easily as grown-ups, so a bit of planning can go a long way to help them stay settled and safe.

At The Little Baby Brand, we know that every parent wants their baby to sleep soundly – even during a heatwave. In this guide, we’ll share simple, practical tips for coping with hot weather and making sure your baby stays cool and comfortable, especially when it comes to summer sleeping.

Why Warm Weather Needs Extra Attention

Babies naturally feel the heat more than adults, particularly in the early months. A slightly warmer night might just mean tossing off a duvet for you, but for babies, the right layers and room conditions make all the difference.

The good news is: a few small adjustments can really help your baby stay happy and comfortable through warm days and nights.

What Should Your Baby Wear to Sleep in Summer?

Choosing the right sleepwear for warm weather is one of the simplest ways to help your baby feel cool and cosy. Here's a handy guide based on room temperature:

  • Over 26°C – Just a nappy or a short-sleeved vest

  • 24–25°C – A light sleeveless or short-sleeved bodysuit

  • 22–23°C – Bodysuit plus a thin 0.5 TOG sleeping bag

  • 20–21°C – Long-sleeved sleepsuit with a 1.0 TOG sleeping bag

Look for natural, breathable fabrics like 100% cotton – they’re soft on skin and help keep body temperature steady. Our collection at The Little Baby Brand includes lightweight cotton rompers, vests, and sleepsuits – all perfect for warmer nights.

Keeping the Nursery Cool – Simple Tricks That Work

Not every home has air conditioning, and that’s okay. Here are a few tried-and-true ways to help your baby’s room stay cooler on warmer nights:

  1. Close blinds or curtains during the day to keep out direct sun.

  2. Use a fan safely, placing it across the room to gently move air – never aimed directly at your baby.

  3. Offer a lukewarm bath before bed – it’s calming and helps gently lower body temperature.

  4. Minimise bedding – often, just a fitted sheet is plenty in hot weather.

  5. Check room temperature using a baby-safe thermometer. Ideally, aim for between 16–20°C.

How to Know if Your Baby Is Too Warm

Babies can’t tell us if they’re hot or cold, but there are a few signs you can look for:

  • A sweaty back or chest

  • Flushed cheeks

  • Restlessness or fussing

  • Damp hair

Feel the back of their neck or chest rather than hands or feet – that gives the best clue about how warm they really are.

During the Day: Staying Cool While Out and About

When you're heading outside, try to keep your baby in the shade, especially between 11am and 3pm when the sun is strongest. Dress them in light, loose-fitting clothes and a soft, wide-brimmed hat. Our baby sun hats and cotton summer rompers are ideal for staying stylish and protected.

If your baby is still feeding, they may want to feed more often to stay hydrated. For formula-fed babies, small amounts of cooled boiled water can be offered if recommended by your health visitor.

A Calm, Comfortable Bedtime – Even on Hot Nights

To help your baby sleep peacefully in the heat, keep bedtime routines calm and gentle:

  • Use soft lighting and minimal clothing

  • Make sure your baby’s sleep space is clear, cool, and uncluttered

  • Trust your instincts – if you’re too warm in the room, your baby likely is too

You don’t need gadgets or gimmicks – just thoughtful choices and a bit of awareness go a long way.

Summer Baby Sleep Safety Checklist

Here’s a quick recap of summer sleep dos:
