Jonathan has gained 1 pound since we've been feeding him "protein shakes". That's a lot in just one week, percentage-wise. We think he's storing it all in his barrel chest. I bet at his next appointment he'll be above the 5th percentile. If you take his current weight and apply it to the 6 month age, he's at the 5th percentile right now. It looks like he wasn't eating enough. I think that was partly due to the fact that he gets distracted easily...
