Picking my nearly 4 year old up from nursery today and was told my son had hit another child during a squabble over a toy. Apparently my son was playing with a toy when the other child came over and a squabble ensued, then some pushing from both of them, culminating in my son hitting the other child in the face. 
My son got a time out and they both said sorry to each other for the pushing but I feel absolutely awful. He’s not been allowed to do his usual Monday afternoon activity, no tablet time or tv time and no pudding after lunch as a penalty.
He’s generally a well behaved little boy and certainly doesn’t have form for this type of thing. I asked after the other child and they were ok but I feel so guilty and embarassed about his terrible behaviour today. The teacher said they made them both say sorry to each other and carried on with their day but I feel so disappointed in what he did.
Nursery aren’t allowed to tell me who it is, although I do know because my son told me. I’m not sure if I should apologise to the mother and make my son apologise to the other child again or if that’ll break confidentiality as it’s supposed to remain anonymous.
I’m so disappointed in him and I thought I’d brought him up so much better.
