DD2 (12) has really long (waist length) knotty hair that is a general PITA. It hardly ever gets brushed unless I give in and do it myself. Getting her to brush/wash/dry it is traumatic and if I didn't insist it would go unwashed for weeks. Last night it was matted underneath which took nearly an hour to get out even with a tangle teaser. When I suggest she has it cut to a more suitable length she says it's her hair so she can do what she wants
. AIBU to insist on her having it cut? Or is she too old for that? 12 is such a tricky age! Thanks in advance.
