This little guy, shown here on his birthday, just had his 9-month check up today. He is up to 22.5 lbs (80th percentile) and is 30" tall (95th percentile).
The pediatrician told us that he will likely be somewhere between 6' and 6'4" when he is fully grown!
But really, I don't want to think about that yet. I'm liking 30" just fine.
