Baby overheating at night: signs, causes and what actually helps

By Stellar Baby Updated 7 July 2026 1 min read

You've gone in to check on them and they feel a touch too warm and a little clammy. It's a common worry, and the good news is it's usually straightforward to sort. Here's what the evidence actually points to.

How to tell if your little babe is too warm

Hands and feet are often cool even when your babe is perfectly comfortable, so they're not the best guide. Red Nose suggests feeling their chest or the back of their neck instead. A bit too warm and damp? This can be a sign your babe might be happy with one less layer or a lighter TOG.

What usually causes it

Most of the time it comes down to layers, the environment, or your babe fighting off a bug. Too many layers or layers to heavy for the temperature are the most common and the easiest to fix.

What actually helps

Matching the layers to the environment will usually do the trick. If you're ever unsure, feeling your babe is the best way to check. And remember, small adjustments go a long way.

When it's worth a call

If your babe seems unwell, is very unsettled, or you're just not sure, trust your gut! Your GP, child health nurse, or Pregnancy, Birth and Baby on 1800 882 436 are there for exactly this.

How the environment fits in

Knowing the temperature where your babe sleeps takes one variable out of the guessing. Orbie reads it live at their level and suggests the layers, so warmth is one less thing to wonder about at 2am.

Common questions

How do I know if my baby is too warm?

Red Nose suggests feeling their chest or the back of the neck rather than hands and feet, which are often cooler regardless. Skin that feels warm and damp there can be a sign to adjust a layer.

Where should I feel to check my baby's temperature?

Red Nose suggests feeling their chest or the back of the neck for the most reliable read. Hands and feet are often cool even when your babe is comfortable.

Is it normal for babies to sweat when sleeping?

Some sweating can happen. If it is persistent or your babe seems unsettled, it can be worth adjusting a layer or checking the environment, and speaking to your GP, child health nurse or another health professional if you are unsure.
