Baby Bulk Up

If I didn't know better, I'd think that John had been sneaking out to eat at GNC. He was supposed to have regained his birth weight (8 lb. 4 oz.) by today's checkup. Since he'd been jaundiced, I was wondering if he'd make weight. Not only did he regain his birth weight, but then some! He's now 8 lb. 10.5 oz. and 20.5" long. What a good eater!
