Hi, Just wondering your advice on how to dress my baby for sleeping.. my house gets really cold (between 10-15 deg) and I Want to make sure she’s warm enough but obviously not too hot.. what clothing and blankets should I be using? Thanks!

It is not possible to recommend specific amount or type of clothing/bedding for each individual baby.
Red Nose recommend that rather than state how many bedclothes can be safely placed on a baby, parents can work out the amount of bedding to be used after considering these factors:

The room temperature where baby is sleeping.
How hot does the baby feel? A good way to check baby’s temperature is to feel baby’s back or tummy (don’t worry if baby’s hands and feet feel cool - this is normal).
Whether the baby has a cold or infection or another special need.
Consider how many layers that you as the baby’s carer are wearing comfortably.
Dress baby and use layers as you would dress or use layers yourself: to be comfortable, neither too hot nor too cold.
Consider using a safe baby sleeping bag (one with fitted neck, armholes or sleeves and no hood).

Dress baby for sleep and add/remove lightweight blankets to ensure baby’s back or tummy feels comfortably warm to the touch.
Remove hats, bonnets, beanies and hooded clothing from baby’s head as soon as baby is indoors.
