Stratton's check up

At 10 weeks Stratton weighed in at 15.3 lbs, is 24 in. long, and has a 17 in. head circumference, he's over the 95 percentile in weight, and head size, and 90-95% in height. He's about to have to switch to size 3 diapers, which start at 16 lbs. (the 3's are leaving read marks all over his thunder thighs). Doc. said he's looking good! Crazy to think that my 10 week old is only 10 lbs. lighter than my 18 mo. old. sheeeshh!
