My 13 year old daughter gets quite hysterical when I try to do anything that involves touching her -brushing her hair, wiping a smudge off her face, cutting her nails, helping her with using a tee-pee brush with her brace. I don't just mean a bit upset - but sobbing and panic-stricken (not angry). I don't understand - I'm not hurting her in any way. She is old enough to do these things independently - so I'm not trying to stop her doing this. But when she needs help - like with using the tee-pee brush, it's like I'm dealing with a baby and not a rational 13-year old. Is this normal? or do you think she's moving towards "odd" behaviour that should be addressed?
