3 year old DS is driving me and DH insane. Constantly throwing toys, hitting, screaming at our faces when he can't get something he wants. We have done everything from taking away his toys, distracting, timeouts etc. he keeps getting back to it. And then on Friday the nursery tells me that he has thrown a toy at another child and it left a mark. He was on the timeout chair when we went for the pick up. I'm devastated. I don't know what to do. I would be livid if I were the parents of the other child. DH is also equally worried that we aren't disciplining enough and what if he does something awful. The only thing left to do is to smack him but we won't ever do that. Please give me some advice I'm in tears.
