As far as the birds and the bees, I thought her school had covered it (as had the books I had provided) and kinda walked into a bunch of stuff by mistake. Let's watch Glee! Wow, let's learn about teen pregnancy! Let's watch Dirty Dancing (what was I thinking?! I think I just forgot) and learn about botched abortions!
However, having these storylines did give us an opportunity to talk about things like not having to do things unless you want to, and protection, and social ideas versus your own ideas of what's right or what to do, and why it's not fair that girls get flack for sex and men don't (at least one decent lesson from Dirty Dancing thank you very much). And why people even WANT to have sex, and why men want it more than girls do... It was pretty excruciating for me, but I took deep calming breaths and now I do feel she trusts me to be able to talk about ANYTHING. Let's hope.
Also, I did find a good way around her asking about me and her daddy and what we might get up to. I basically told her that a lot of this stuff was personal, and people liked to keep it private because - just look at HER reactions - sex was a tricky subject for a lot of folks. And the more she thought about what I and her father were doing, or her grandparents, or other people she knows, the ickier it would probably make her feel. So it was better to keep it general and less about specific people. She agreed and thank goodness has not again asked me, "So have YOU..."
As far as moodiness, I more get the Disney tween "I know more than you eye roll eye roll" attitude, which I counter by simply refusing to deal with it. Wanna be snarky? Guess you're not getting what you want! Stomping around about chores? Too bad! We're also only three, and we have to function as a family, which means her pitching in too.
Not looking forward to actual puberty AT ALL. But then she isn't, either.
