Emmy needed a neck and throat Xray. Turns out we know the Xray technician, and it was a slow time of day, so she let me and Emmy come back to see Emmy's xrays on the computer screen. It was fascinating to show Emmy her skull, neck, collarbone, ribs, etc. in the photo and then trace her finger along the bone through her skin so she could feel the bones she was looking at. While showing Emmy her teeth, I saw this second row of teeth directly underneath them. I said "Emmy, look, these are your grown up teeth getting ready to push your baby teeth out of the way. Wow. Look how close they are. I'll bet you start losing some teeth soon." Emmy was speechless.
When we got in the car, Emmy wanted to call Mama and tell her all about the xrays. She was so excited, all she could say was "The adults are coming. The adults are coming. The adults are coming!"
