Jonah's 1st Dentist Appt

We took Jonah in for his first dental checkup today. He did great!
Here he's watching a Spiderman cartoon - 21st century dentistry! He
has a permanent tooth already. Typically kids are 6 years old when
they get those not four, but he has consistently gotten his teeth
early. I wonder if this means he will loose baby teeth early? The
dentist said to be on the lookout!
