Christ on a bike!
I started having my underarms waxed at 11 or 12 (when most girls start shaving if they have hair yet), because Mum wasn't going to let me shave it, and I didn't want to put a razor blade near my skin. I was 15 until I did anything to my legs at all: a half-leg wax. I never wax higher than my kneecaps.
I'm 21 now, and I have my underarms waxed once a month (although when I was younger, the waxings weren't as regular, obviously), and I have my legs waxed every 4-8 weeks in the warmer months.
I'd rather swallow razorblades than wax or shave my pubic area. I'm not a terribly hairy person, but I am a brunette. But you know what? I don't care. Why are women expected to remove all their body hair anyway? I think this whole removal-of-pubic-hair trend is sick and just plain stupid.
And on an eight year old?!
