Luckily, it turns out that she isn't making enamel. See that? My first thought was 'Oh thank goodness, I'm not as bad of a parent as I suspected' THEN I started asking questions about how to save her teeth until the adult ones come in (Let's hope the adult teeth get the message about the importance of enamel, no guarantees!)
Ugh, two year olds. They're so small in very large dental chairs, holding onto their bears and periodically doing a little self talk. "I'm okay, Mommy. I'm okay at the dentist." And I'm there trying to be all positive and calm and freaking out inside about how tall she's getting and how tiny she is in the enormous chair that seems cool because it lays back into a bed but we all know what happens when the dentist lays you back and says 'open wide!' and she has no clue.
