Luke's stats at 6 months

Luke had his 6 month check up last week and he is doing very well. He weighs 19.5lbs and was 27.5 inches and for everyone on my side of the family....his head was only in the 80%! He is rolling all over the place these days and trying to move around on the floor so we think he will start crawling soon. I can't believe he is already 6 months!!
