Hi there. I have a ten week old baby and o don’t know how to get her bedding right for qld temperatures. The room temp is 24-26 degrees at night. I dress her in a bonds short sleeve no-leg suit, a miracle wrap swaddle (I think the 1 tog ergo sleeping bag might be too warm for her), sheet and cot blanket al tucked in to the bottom of the cot. I am on a forum that talks a lot about layering blankets and sheets and they seem to have much more bedding than I do. Can you please help? I’m very fearful of overheating her!

Red Nose does not recommend specific bedding/clothing for specific room temperature, rather recommends dressing baby depending on the ambient temperature.

Red Nose recommends using light weight blankets, which can be removed as the weather gets warmer.
Many baby’s will sleep without use of blankets as they grow & start rolling in their cot.
Dress baby for sleep and add/remove lightweight blankets to ensure baby’s back or tummy feels comfortably warm to the touch.

Babies will lose excess body heat via their head & face, so it is important to keep baby’s head & face uncovered during sleep.
Here is some information from Red Nose web site.
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

Babies control their temperature predominantly through their head and face. This is why we recommend that you put baby to sleep on their back with head and face uncovered.
Red Nose does not recommend a specific room temperature for baby’s sleep. This is because there is no evidence to show that maintaining a specific room temperature prevents sudden infant death.
Dress your baby as you would dress yourself for the temperature of the room – comfortably warm, not too hot, not too cold.

In warmer weather, you can dress baby in a sleeveless and legless onesies, or just a nappy and singlet. For cooler weather, a full suit will keep baby warm.
