Oh dear. Just when things were going so well...DS 3yo has been back at pre-school for 3 sessions this term, and the supervisor called me to one side to say he has been hitting other children quite hard. She didn't think it was in retaliation (not that that would be ok but it might be a reason why!) I was mortified and didn't know what to say - except sorry. He is a loving, caring, considerate little boy, but has started asserting himself recently (saying very definite NO to me when I ask him to do things)and being more of a handful, but I hadn't noticed hitting particularly.
Any advice gratefully received or just your thoughts. I have spoken to him tonight about it but just want to nip it in the bud.
