I used to be warned (including from my mother) and worried myself about the older kid thing, but there are kids in my DD's class and grade that swear, watch R rated movies are exposed to stuff I wouldn't let her be exposed to so I've gotten disillusioned with that idea. She notices and talks about everything, so I have to deal with it anyway, talking through things etc...so why not let her experience a more comfortable intellectual fit while we're doing it? I've grown into this opinion over the last year.
