A long time ago, Red Chief lost his four front teeth (in first grade). Slightly less long ago, he lost the first of his next group of four teeth. Then—nothing. We waited over a year for that adult tooth to start coming in, but things finally started moving along again recently, and the tooth fairy has made two visits this month (the end of third grade for him).
Tiger Lily will probably start losing teeth soon too. I will be sad to see her sweet little baby teeth go.
Under no condition is Baby allowed to start cutting teeth yet. Someone tell him that.
