I've noticed that my baby had cold arms and hands when he was in a 2.5grobag despite wearing a long sleeved vest, bodysuit and mittens. Any other solutions? His feet and body are warm as they are covered - just the arms and hands. Is this a reason for unsettled sleep as he does turn and twist a lot and recently flipped to his front as he does not normally do this in his cot. He is almost 5 months and 2 weeks.

Any other solutions? We don't want to put the heater on all night as it can be drying.
