It's three days before he's 20 months, but it was more convenient to get him weighed and measured today than wait until next Tuesday for the free drop-in clinic.
He's therefore out of size 1 clothing for age and height, but not for weight, which explains why his size 1 shirts still fit him but not his pants. I figured he'd be in size 2 by Christmas. I think I'm right. He's definitely taking after his father with regard to body type. Poor me. I'm going to be the shortest in the family.
