I think DD might have been cold last night and was wondering if there were any tips for keeping her warmer. It was a cold night last night and she woke up a couple of times, when normally she doesn't, so was thinking cold. She has a 2.5 tog sleeping bag, and babygro and vest on. There seems to be no point putting a blanket on her as she can cover the surface during the night. Any recommendations as to how to keep her warmer? I'm not keen on keeping the heating on overnight partly for the bills and partly 'cause it gives me a headache.
