Band 20–22°C
Borderline with the 18–20°C band. Stick with the setup above — we stay on the lighter side, so add a layer only if they feel cold to the touch.

Safe sleep checks
- Always place your child on their back to sleep.
- Check for overheating by feeling the chest or back of neck. Remove a layer if hot or sweaty.
- Do not put a hat on your baby indoors or for sleep — babies cool down through their head, and a hat can cause overheating.
- Do not use a sleeping bag with a cot duvet or loose blanket.
- These are general guides only — every child is different.
- Ideal room temperature for sleep is 16–20°C.
- Stop using a sleeping bag if damaged or if your child can climb out of the cot.
