We've started to notice Acer's ankles peeking out under his pants lately and wondered why as I haven't had a mad shrinking fit with the washer, and we'd just bought him new pants for school in the fall.
Well it seems he's grown an inch and a half in the last six months!
This explains how he was able to gain three pounds and still look as slim as ever. I was actually worried because, going on weight alone (he's very muscular) Acer's weight and old height put him in the obese category for BMI calcualtions. Now that we know he's 39.5 inches, and 37 pounds, he's in the 80% category which makes me much happier.
Now I just have to find longer size threes or size 4's made for boys with no butte!
