For the last few weeks, my son who has just turned 3 has started pushing others at nursery. He has a speech delay and can get frustrated but his understanding is pretty good. I’m at a loss what to do and I feel awful for the children he pushes. He usually pushes a child when they have a toy that he wants. The nursery gives him time out and he cries but then does it again later on. I just don’t know how I can nip this behaviour in the bud. I’m wondering about starting a behaviour chart that he fills in when he gets home but I’m not sure he’d understand the concept. He goes to nursery for 3 half days a week.
