She is 2.5 years old. Very "normal" in most ways, typical 2.5 year old except when she is angry. When Very angry or frustrated, she will sometimes in the moment of rage pull her hair. It's quick but she does it so hard that it comes out of her head. Some days 2-3 times, some days not at all but over the past year, a fair amount of hair has been pulled out! She also only seems to do it in front of me. When shes just with my husband, she doesnt do it, when my mum has her once a week and my MIL one day a week, she doesnt do it in front of either of them. Is she doing it for my reaction or is there something bigger going on?
