Hair brushing most definitely should not require window closing least the neighbors call the police. At our house this could possibly occur. Call it sensory issues or waiting too long to brush hair. It is a major ordeal. So we put it off. And it gets worse. It’s as if she has a gun shot wound. The screaming is loud accompanied by,”Stop it mommy. You’re hurting me.” Without the visual, that doesn’t sound good. So we avoid hair brushing. We have alternatives I suppose. Shaving the entire head or sound-proofing the house. We’ll probably just stick to putting it off.
