OT - short boys

Caleb has always been 10th percentile for height. He's usually the smallest in a group of kids about the same age. Kids who are 6-12 months younger than him are taller. He's 2 yrs, 4 mos and still wearing 12 month size pants. However, his pedi has never been concerned, as he's never fallen off his growth curve. We have no information on his birth father, so we can't look to that for where he might be, height wise. His birth mother seemed to be around 5'6". So who knows, maybe he'll have a growth spurt.
