DD1 is 2 years and 4 months. She's a happy, outgoing girl and very settled at home and nursery. But she won't stop playing with her hair and getting it tangled, and she's losing so much hair through this it's getting really noticeable. On one occasion a couple of weeks ago she actually pulled a whole large clump of her hair out at nursery by twisting it so much and she now has a bald patch. She constantly getting tangles in her hair where she twists her hair around, and invariably hair is falling out each time I try and untangle these knots. Her hair is too short and fine to be able to tie back (I've tried) and she takes out clips and hairbands if we put them in. We've tried giving her a doll with long hair instead to play with (on advice of her nursery) but it's not working. It seems to just be a habit although she does it more when she's tired. We try and stop her doing it as much as we can but I've got a 10 week old as well and invariably can't always stop her playing with her hair. Any ideas?
