He's not as big as I thought he was going to measure!
Here's Wesley's current measurements (roughly...)
His seated height is 19", and about 18/19" heel to hip. That makes him about 37/38" tall
His inseam was 11", his foot 6", and his arm length (shoulder to wrist) was 12". Shoulder to bottom (seated) was 12".
His waist (over a few layers) was about 16" and his chest about 20" (over a sweatshirt).
All of these could be off by an inch or several inches... we're really not sure because it's hard to measure a wiggly kid :) But those are close enough for us to be able to make sure we bring back clothes that are at least close to what will fit him! :)
If anyone happens to have some size estimates, that would be great! I'm still thinking that a size 4 would be roughly the right size, though his pants will fall off :) One of the shirts he was wearing was a size 18 months, but it wasn't exactly fitting him very well...
