We were told by our doc to stop swaddling because he's showing signs of rolling over from back to front (already rolling tummy to back).  Our room is about 70 degrees and I currently have him in a long sleeve footy pj outfit and a fleecy sleep sack jumper thing. Is that normal?  His core feels nice and toasty,but his cheeks are a little chilly in the am.  He's ten weeks and sleeps in his crib.   What are your kiddos wearing at night?
