Hot weather with a newborn: tips to keep cool

There’s a bee coming towards your baby’s tiny foot, you can’t work the parasol. Here’s how to navigate hot weather with a newborn.

Here are our newborn SOS tips when it comes to hot weather…


Under six months, babies’ skin contains too little melanin to give any protection from the sun so they shouldn’t be exposed at all. When they are in the pram, attach a clip-on parasol or sunshade.

Don’t cover the pram with a blanket, towel or even a trusty muslin because your baby can overheat this way.

Water, milk and what to do about hydration

If you’re breastfeeding your baby, they won’t need to be given water. They’ll probably just want to feed more often.

If you’re formula feeding, you can offer a few sips of cooled boiled water when it’s hot in between feeds. It’s important that water doesn’t replace your baby’s milk feeds.

Room temperature

The ideal room temperature for your baby is between 16°C and 20°C

Ask any new parent and they’ll tell you how much time they spend worrying over the temperature in their baby’s bedroom. The ideal room temperature for your baby is between 16°C (61°F) and 20°C (68°F). The best way to measure it exactly is with a thermometer.

During the day, keep curtains or blinds closed, open doors and windows, and even put a fan in the room to circulate air. Don’t leave a fan in there when your baby goes in to sleep though, as that can be a danger.

Baby summer clothes

You had your baby at the peak of summer and now you have some new outfits ready for them, courtesy of generous friends and family. Yet the only thing your baby really needs right now is their nappy.

Even for sleep, a vest or just a nappy are fine on the hottest nights. You’ll get to those lovely outfits later, when the weather breaks in three days’ time – this is the UK after all.

Baby summer carriers

You might be keen to try babywearing but are worried about your poor baby getting sweaty in the sling. You could choose a carrier made from lightweight nylon rather than a heavier fabric. Read our article on everything you need to know about slings and carriers.

But whatever you do, always stick to the manufacturer’s instructions and follow sling safety guidance, TICKS, which stands for:

  • Tight for adequate support
  • In view at all times (this refers to your baby’s face)
  • Close enough to kiss (your baby’s forehead or head)
  • Keep baby’s chin off their chest to ensure breathing isn’t restricted
  • Supported back so the baby can’t slump and restrict their airway.


What do you actually do with a newborn baby in the summer months? It’s a good question.

Babies are often happy with the simple things in life. You could try lying them down in a shady part of the garden or park and blowing some bubbles over them.

Or you could simply put them in the carrier and head off for a lovely walk. Your local NCT branch is a great way to make friends with other parents-to-be and new parents in your local area. They’re running online events for parents so find out what activities you could join in with.
