I need some advice for my 14 month old, for the past month or so he has been repeatedly hitting/biting/grabbing other children's hair! I always intervene and say 'no we don't hit etc' and move him away to something different but sometimes he just goes straight back to try and do it again. I'm just at home with him so wonder if he doesn't understand how to interact with other kids as he isn't around them as much as if he went to nursery. Any suggestions on how I can help him learn? It's really upsetting me and I'm now avoiding going places where I know it's likely to happen. He's seems the only one I know who does it!
