my grandaughter aged 4 twirls and twists her hair into a large knot always on the same side. this has resulted in restircted hair growth on that side and my dau has sometimes had to cut it as it is impossible to untangle. this is a comfort thing and she only does it when tired (she will also twirl yours if sat next to her) we have a photo of her in the womb (3 d scan) showing her doing this then. How do we stop it as dau is now at wits end as people have started to comment on different lenghts of hair ( we cant keep croping it short like a boys ) any advice welcome. thankyou
