Today I took ds1(4) and ds2(2.6) to the playground. There were two other boys there who were probably slightly older than ds1. They knew each other and were playing together with one nanny and one mother on a bench nearby. I teach my boys to play nicely with others - no hitting, throwing sand, meanness(sp?), etc. So these two boys are being openly hostile in what they are saying to my boys, but are not hitting or doing anything that I can intervene with. It was very much an "us" vs "them" mentality. The two boys played a bit on, their own including throwing sand and hitting the playground equipment with their large spades - one of them even managed to accidentally throw sand into the other's face. Later I caught my boys throwing sand at one of them and told them off. The two boys then proceeded to aggressively tell my boys off for throwing sand at them. I pointed out that my boys were only copying them. ds1 tried to get them to play with him on a "plane". He wanted to be a driver but they said they were the drivers; later he said the plane was broken and they said it wasn't, etc. I know boys are like this but it is heartbreaking to see ds1 constantly being dominated. Is this how it is always going to be? Is there anything I can do? I don't want him to be like them but I don't want him to be dominated all the time either
