Hi, we have a new born perm baby, who was born 36weeks and now home at 38 weeks, our room gets upto 26 degrees in temp between 1-530pm and is very hot compared to the other rooms. We have a Dyson tall coolran running on auto to help regulate the room My. Qs are is how hot should the room get ? She is dressed in a singlet, onesie, muslin wrap and cotton blanket... Is this too much ? Thanks

Red Nose does not recommend specific room temperature or use of heating/cooling overnight,
but recommends dressing baby in relation to the temperature of the room.

It is not necessary to monitor the room temperature or to leave the heating or cooling on all night, as long as the baby is dressed appropriately for the room temperature: Dress baby as you would dress yourself – comfortably warm, not hot or cold. A good way to check baby’s temperature is to feel the baby’s back or tummy, which should feel warm (don’t worry if baby’s hands and feet feel cool, this is normal).

Dress baby for sleep using layers as you would dress or use layers yourself: to be comfortable, neither too hot nor too cold - add/remove lightweight blankets to ensure baby’s chest feels comfortably warm to the touch
A good way to check baby’s temperature is to feel baby’s chest or back of neck, which should feel warm (don’t worry if baby’s hands and feet feel cool, this is normal).
Ensure baby’s head is uncovered - no hats, bonnets, beanies or hooded clothing.
