Aiden's new stats are as follows. As of his two month doctor's appointment, he weighs in at 13 lbs. (75th percentile) and 25.5 inches (97th percentile). So needless to say, our tiny son is turning into a big boy! We are really enjoying watching him grow and although it's sad to see him leaving the newborn phase it is a lot of fun to see all the ways he is changing.
