DS is aged 4.3. He has two regular friends of similar age who he plays with at various times. One is a boy and the other is a girl.
He is fine with girl playmate. But not so fine with the boy, who lives just round the corner and who he has known for just over a year. He doesn't want to play with him anymore or have him come here.
I have seen a thread like this before in the past and I don't want people to jump all over this thread like they did on that one, but I'll just say that there are problems to do with the boy's behaviour and communication which make play between DS and him difficult and this is not helped by the mother, who is overprotective and overpolices their play - often to the detriment of my son.
The mother wants them to be "like brothers", but DS is not having any of it and flatly refuses to go there now. He says the mother is "annoying". SHe certainly is a bit full on, the other day she practically cornered DS and asked him right up in his face "Do you like XXX(her DS's name)" This made my DS very uncomfortable.
DS starts school this September and I am sure will make lots of new friends there.
