One Month Doctor Visit

I took Jack to his one month visit today. At 5 weeks old, he is 12.1 pounds and 23.5 inches long!! His head measures 15 3/4 inches. He's such a big boy and my arms are definitely feeling it! His height is in the 95th percentile and I have no clue where it comes from. His dad and I are both short. I have a feeling that this kid is going to tower over me and probably sooner than I'd like!
