I've been putting her down in cotton footie pajamas (carters) and a cotton sleep sack (Halo, not the swaddle kind). Should i be dressing her warmer--maybe in fleece jammies or heavier sack? She seems OK (sleeps fine, etc) but her exposed skin (face and hands) feels pretty chilly when we wake her up in the AM.
Edited to add she's 3.5 months old.
