I know that some kids do and that it is part of finding their boundaries and learning how to behave BUT it is so mortally shamefull and embarassing when my ds clobbers innocent sweet little boy on the head during circle song time at playgroup, and i have to do the walk of shame out of there, feeling those silent smug thoughts - 'oh, thank goodness my ds/dd doesn't do that'. He has a great report from nursery, joining in, sharing, getting on with the other kids, however when he is with me, he will sometimes hit and push kids who are a little younger than him and often refuse to share. I know there will be lots of mums who will sympathise when their sweet little darling turns into a little thug. I am hoping this is short lived phase and will pass soon but i am dreading going to playgroup next week. Any words of empathy most welcome.
