Anyway, at 9 weeks old, he weights 13 lbs. and is 25 inches long. 75% for weight, and 90% for height. Hmmm....only in this family do we worry when one of our babies is *only* in the 75th percentile for weight! My boys are always OFF the charts! What's going on!! Anyway, he's doing great. My little sunshine. Or monkey....my little monkey. Costume #1 of 3. Stay tuned.
