Where's the supportive parenting sites for parents of teens, anyways?
. Oh my gosh, I feel for you shez!!
I very much relate to the difficulty in taking away a priviledge that in turn is walking a thin line in not depriving the other. I've sometimes had the non offending sibling check their stuff of potential contraband(for lack of a better word) with me when not in use to prevent misuse from their sibling.
