Baby’s body temperature in winter?

I often felt my baby's body's cool during the night.He's four month old. He wears a shirt and cotton pajama and also snow suit to bed. I also put a cotton duvet over him. We used a heater as well. I don't understand why his body seems cool. In summer he was warm all the time. Does this happen to other babies? Normal?



Appreciate for your answers.

What temperature is his room?

Lily felt cool until I got the right temp and number of blankets/clothes.

Ideally the room should be something like 18 degrees, ours is about 19 and she has flanellette sheets, 2 cotton quilts, and occasionally an aircell blanket folded in half. She is also swaddled and wears a cotton singlet and either a AIO or bodysuit and pants. I dress her warmer if it is really cold. Her room gets really hot in the day due to direct sun from sunrise - 2pm and can get to 28 degrees without the windows wide open! Even in winter but at night it can drop to 7-8.

A snow suit?

I'm just about to go to bed but from what I recall wearing a (waterproof) jacket or a snow suit to bed is not such a great idea - you would be better off with a sleep sack or more normal clothes and more blankets. Brains a little fuzzy at the moment but I remember wearing a jacket to bed once as a child and ended up freezing, told my parents about it in the morning and they were like "No wonder you were cold!". Gah, can't think of the proper reasoning at the moment - something to do with the waterproof jacket restricting the ability of the body to regulate the air around it but will look it up properly in the morning.

Another thing to consider is if you can't keep the temperature in his room above 18 degrees perhaps put a beanie and socks on him - those are the parts of the body where heat escapes the most.

Have you got any woollen blankets? You'd be surprised at the difference as I noticed when I was bringing Cooper into bed with us sometimes he was quite fidgety and I checked and he was a bit cool even with his sleeping bag on and being wrapped, cuddled next to me with our duvet. So I started bringing in his woollen blanket and the difference was amazing, and I even shared it with him and it's so snuggly warm in comparison to a duvet. I'm even thinking of putting one of our bed so DH doesn't sleep with his side of the electric blanket on all night.
