DD(5) currently has a friend at our place for a sleepover. The girls are both 5 and my DS is 3. Ever since the friend arrived last night both girls have been a bit mean to DS saying things like "we don't want to play with you" or "No DS, you are too little to do this with us" or "get out of my room". While I understand they are girls and they are a little bit older I'm not happy with them treating DS like that so I've been stepping in a bit and telling the girls they need to include him. After a while he tends to leave them alone and do his own thing anyway so they do get their own time. He has been annoying them a bit sometimes so I've also tried to keep him out of their way at times.
I'm just wondering what others do? Am I being too strict my making them include him? I'm interested to know how this plays out at other peoples houses!
