My dd1(6) has started nail picking, both on her fingers and toes. I think it started somewhere in the autumn, because that's when I realised all of a sudden that I hadn't cut her nails in ages. Her nails are now extremely short and I worry a little that she'll hurt herself in the end. I'm also worried about why she's doing it, but she says she doesn't know either.
Any suggestions as to how to get her to stop?
