My DS (just turned 2yrs) has always been a very active, boisterous boy and is also quite big for his age (looks more like 3 yrs) and is at the age when he REALLY doesnt understand sharing. We were at our Mother & Toddler Group today and (while I wasn't looking) he apparently grabbed a little girls hair and yanked it really violently when she came near toy he was playing with. The girl's Grandmother was rightly upset and told me about it - I took the car away from him, told him off in front of the girl - and then immediately took him home - he KNEW he was in trouble and cried all the way back. When I got home (this is VERY unusual for me) I immediately started to cry - I felt ashamed that my son had behaved that way as he has never been so vicious before (although he does have an assertive personality) and I also felt (rightly or wrongly) that his behaviour was a reflection on me - even though I know it is not behaviour that we tolerate or encourage at home. I know that the fact that the Grandmother was so cross (it almost seemed directed at me rather than my son's behaviour)was partly why I was upset. Now I am worried about going back to the group because it is very hard to keep my eyes on him every second that I am there, but it is my only respite from constant childcare all week. Any thoughts?
