Very well done Barb.But you can try to teach them to do the right thing.My middle dd has friends who end up sneaking off to play with each other (They just did this to her this week right after lunch).Sometimes it is hard to be a kid so alot of times i end up letting all of the kids here playing with each other.But i have noticed it can get harder when they get older and start to out grow each other too.
