baby born early feb…what should they wear?

my baby is going to be born early february and we live in canada. so cold winters.

how should i dress baby at night? i don’t want him to be cold, but also don’t want him to overheat. tbh i keep my house fairly cool. 19-20 degrees at night. should i layer? socks? onesie? sleeper? etc…i will be using sleep sacks as well.

when we go out i was thinking of buying a car seat cover….but how should i dress him under it?
