Crawling, pulling up, and Dr. appts!

So Christopher decided to start crawling when he was 5 months 1.5 weeks old. I have video, but I'll have to get it off the camcorder. Well a week later I went in to get him from his nap, and this is what I found! He has been pulling up on everything since. We had his 6 months appt. the other day. He is 16 lbs 11 oz (between 25%-50% percentiles) and 27 3/4 inches (95%). So he is long and somewhat thin. Great I'll have major problems with pants fitting just like Alex. Anyway Alex also had his 3 year appt. He is 33 lbs (50%-75%) and 3 ft. 2.75 in. (75%).
