Definately OK to take her out - they need as much fresh air as possible even in the cold. She sounds like she is very well protected - you can check her temperature by feeling the back of her neck - if that is warm then she is warm. I used to worry about Charlotte being too cold (and she was born in July - albeit a cold one) and one day we got home and she was actually sweating. She seems to take after her Daddy and not feel the cold like I do, so I am now more carefgul not to overheat her. YEsterday we went out and it was very cold, and she was wearing her day clothes (vest, long sleeved top, jeans and booties) and then her winter coat with a hood and a wooly blanket with a pram blanket (folded in four). My pram is the old fashioned carry cot type which is wind proof and she was perfectly warm and had lovely little red checks when we came back.
