Maybe that's why the other parents send them outside!
DD has a friend who has an older brother she fights with constantly, so I think she thinks that's normal.
Well, I would start by limiting the amount of time they are allowed to play inside.
no real advice.
Just to make sure I understand, you are expecting the visiting kids and your older kids to play with the younger kids? I can't say I have any experience with that, either from my own childhood (and we did have piles of kids who all played in the hood, as well as friends home frequently) or dd's childhood.
IMHO, if the two teens are hanging, they should be free to go hang by themselves in your 13yos room, ditto for the other "pair." The other two kids could either play together or find something else to do. I can't see why the older/other kids should have to entertain them.

My kids (and I) have been told that if they are going to play outside, that they need to play with everyone, and they need to share everything, with everyone.
I wondered if this would come up after i posted...
Same here, when mine are all outside playing they must all get along and share.
