I recently had my 9 month check-up and the updated stats are: 83ed percentile for my head size (man this thing keeps getting bigger), 42nd percentile for length (I had a pretty big growth spurt in the last three months), and weight was 15th percentile (I was at the doctor for this check-up while I was sick and I hadn't had any real food for the last 3 days, as well as an earlier illness the previous month). We think the number may be a little off, and we'll see a difference at his 1 yr. check-up. I have an appetite, but it looks like I might be built like my Dad.
