My LO is big for her age and she has for the last 4 months or so been guilty of hitting. She is 21 months now. She regularly hits us, her friend and the nursery staff. It is always when she is being told No or being diverted from something she see's as good fun or when she wants her own space. It is actually getting very bad and she does not get bothered by time out. She never seems remorseful at all. I always make her apologise but her little friend is actually now scared of her. It is very upsetting to see her hurt other children. She isn't bothered when i tell her No we don't hit either. Any suggestions? I feel mortified.
