The appointment was pretty neat since the doctor really interacted with him. He asked Henry to point out various parts of his body and let him play with his stethoscope. Henry was a bit stand-offish at first, but warmed up to him pretty quickly.
He did have to get a few shots, which was not fun. I imagine that this will be the start of him dreading trips to the doctor's office, since he could get a shot. But he took it very well and cried only a little bit. The Curious George sticker that he got from the nurse after his shots helped dry up his tears, as well!
