At soft play (yup, you can see where this is heading)... DS 12 months crawls down a tunnel where ALL the soft play pieces and balls have been barracaded into a den by 2 boys approx 3 and 4. DS climbed on to one of the pieces which had fallen down from their "wall". Bigger boy tries to pull it out from him. I say "don't pull it away from him, he's playing with it, we need to share". The boy said "No it's ours, he can't have it" and carried on tugging. So I said again "no, these things are here for everyone, you need to share". The child ignored me, and pushed my son and made him cry. I said "that's naughty" but took my son away because I couldn't see how else to handle it. About 5 minutes later I saw a similar interchange with another little one (but no mum present like I was with DS), and then again another one a few minutes later which made the little girl cry. All in they blocked the tunnel for about half an hour and had complete monopoly on all the pieces and balls for the air machine. (gee this is sounding trivial). Anyway, how would you have dealt with this? I'm not sure I'm giving my son the right message by saying you let the "bully" (can't think of a better word so please don't flame me) get their own way.
