DD lost her first tooth recently; she was five years and one week old. It was, like, THE most exciting thing EVER. I totally wasn't ready for it. In fact, I kind of freaked out to my friends for a couple of days while I was waiting for it to fall out. She has a second one that's loose but hanging on pretty strong. I think she got her teeth early; I've heard there's a correlation between age teeth came in and age teeth come out. I'm not sure if that's accurate, though.
