I do mean the ones that come round on a regular basis, not the first-time-overs!
I never thought this was odd, or unreasonable.
Except that I was talking with a good friend about it, and she thought I was a meany, who wouldn't "let kids be kids".
When there are extra kids around, be they family, or friends of my kids, I treat them all the same. My DD is 14, my DS is 12, and they have friends around prety much every day. I also have 4 nieces (1,3,4,7) who are often dropped off.
I expect all kids to follow the house rules, and they do. If they are there at meal times, they are welcome to stay. If they don't like what is on offer, I usally have an alternative, but I don't do the 6 different meals for six kids thing.
If I come home with a van load of groceries, I expect all kids to help unload and put stuff away. Even the little ones can put the potatoes in the potato box 
If they sleep over, I expect them to help deflate air matresses in the morning, or fold up the couch, and to help tidy up.
I'm not a slave driver or anything, and I spend a lot of time with the kids doing things, like going to the beach or hiking or painting. I spend a lot of time talking with them too.
I just don't let them get away with any behaviour that my kids aren't allowed. They have to follow the rules and be accountable, or they don't come back.
Would you be cross if your child was asked to help out when they were at someone elses house? Or if they had to follow house rules?
AIBU?
