Hello, my dd is 4 soon to be 5years old, she's just started repeating what she says in a whisper to herself. In addition, she bites her nails and surrounding skin and her behavour can be erratic - and she grimaces sometimes too. I've spoken to her school teacher, but she doesn't seem to think there's anything too unusual about these things.. should I seek medical advise, I'd like to get her help if she needs it. I'm afraid, though, of labelling her with something unnecessarily, what do you think?
