Teeth!

Holy Cow! Reagan has molars. Tonight, I was brushing her teeth and wanted to look at her back tooth that had a dark spot on it. When I opened her mouth, that's when I saw it. The back bottom left molar was half way through. Then I looked at the rest of her mouth - all her back molars are in except the bottom back right. What!? Wow! Now to figure out what these things are called. I can't believe it.
