I'm with you on the obnoxios teens who don't really want to be there anyway. Seen enough of them when camping myself, but not all kids are like that!
I have to confess though, the first time we took my eldest camping, he was just about 4 months old and had constipation. Must've kept most of the campsite up that night with his rather noisy struggles to poo. Took him 2 1/2 days to manage this feat so I was pleased we were moving on each day [:I].
Probably more detail that you required, but I can see that some folk would rather avoid this kind of thing [B)]
