My DS is over 40" I'd say 41-42. He weighs 45lbs but has always been solid, not fat. Broad shoulders and all. The preschool sent home a letter saying he is in the obese range. Wtf? His doctor said he is average in both weight and height! He doesn't eat a ton of junk or anything really for that matter. I'm a little upset about it.
