From newborn my dd liked to twirl her hair whilst sucking on two fingers, which I didn't have a problem with. However now she has started pulling out the hair on either side of her head. Its done when she is told off/told no and then sucks her fingers with the clumps of hair caught in her fingers. She looks really strange with bald spots either side of her head and a tail down the back. (I'm getting it cut on tues) But I just wanted some advice on why she does it and how to stop it. She also bangs her head on the floor when told off too. God she sounds weird, but she's a happy girl most of the time. has anyone else experienced the hair pulling out?
