DD is 6 so I should know this by now, but I'm always unsure! When it's warm outside I just strip her down to her underwear. But what do you do when your child has a fever in winter, particularly overnight when it's really cold? She usually sleeps wrapped up in the duvet, when she has a fever I have to peel it off her once she's asleep but she will wrap herself back up every time she wakes. I've tried giving her a sheet instead but she gets upset and wants the duvet or a blanket. Am I right to still put long PJs on her?
