I was told when i collected ds today that he had been hitting other children and a teacher today, and this wasnt the first time. This was however the first time id been told. He didnt get given a sticker today, as they only get thm when they are good. However he does usually get one, so i have no indicator that hes been naughty other times. I coudlnt stop to discuss today, as when i was told there was a queue of other mums behind me, and dd waiting in the hall. Im thinking that i will stay with him at the next session/few to see what is going on, but am feeling really upset that he has done this, and am not sure what to do for the best. he doesnt do it at home anymore, although he has in the past. Is this a usual thing for a three year old?
