I never seem to feel confident about ensuring my baby is at the right temperature!
Unfortunately the room she sleeps in (she's currently in with us a she's only 8 weeks) is a cold room. It doesn't get the sun all day which doesn't help and even though we constantly have the heating on (albeit low at night), I still don't feel confident I'm getting it right.
I swaddle her in either a cellular blanket or a large muslin, then put another cellular blanket over the top.
Does that sound enough?
