My dd is just 4, and over the last couple of days has started to want to carry a blanket everywhere. It's an old one that she had on her pram when she was a baby, and she's used it in her doll's pram, but now she's snuggling up with it all the time, and insisted on taking it to bed last night. She's never bothered with a comfort blanket before, although she has a special cuddly toy that she snuggles with, and I'm wondering why she's started to do it now. I don't know whether to let her have it, or to stop it before it starts.
