My three year old hits, grabs my hair, or tries to scratch my faces when he gets mad at me. Is this normal?

My 3 year old will hit me and pull my hair when she gets mad. She has a major anger issue, and all the people saying your kid can only do what you let them, trust me I've done EVERYTHING i can to stop this behavior...charts, token boards, positive reinforcement for good behavior, negative for bad, I am a one to one behavioral assistant and am trained in ABA and it is HARD to get her to calm down when she has a tantrum. I've done everything from ignoring to literally holding her down because she was really hurting me and destroying anything around her. I understand what you are going through because I am too. All you can do is keep trying things to change the behavior for the good. Time outs dont work for me because i would have to hold her in the chair and i felt almost abusive when i would do that. All kids are different and they need to be handled differently. All you can do is keep trying to find what works for your child and dont give up. Be consistent with what you do try, and always stay calm. Yelling at them won't help and getting stressed out won't either, trust me. Good luck to you and God Bless
