1st world problem really- We were out yesterday in the kids playroom of an art gallery. DD (4) had spent ages building a house with some big foam blocks when another child runs in (probably 5/6 ish) with a big familly group and knocks it down I tried to get him to say sorry (nicely!) but he ran off and none of the 3 adults who were with him intervened. Anyway helped DD stop crying and build it back up which we did about 15m later same boy knocks it down again! This time his Dad says "Oh dear lets build it again" but DD is properly upset and at no point does any adult in the group get the boy to apologise. If either of my 2 did this I would pull them up, get them to say sorry to the child they upset and give them time out. It has really got me riled DH says its just different parenting and I shouldn't interfere AIBU?
