He's between the 10th and 15th percentile for both - this has been his growth curve since about 6 months, maybe earlier.
ETA: He lost his coat at nursery school the other day and I asked the teachers if maybe one of the other kids took it home with them. They responded with "OH NO, no one is small enough to fit into Hank's clothes!" His morning teacher told me that he and another little girl are the smallest in the class... umm the other little girl is 18 months. He is three.
