Colin turned five moths on Tuesday. He has been barrel rolling and scooting around for a week or so (also getting up on his knees), but Monday night he really crawled. Now, by the end of the week, he is getting much faster! He went to the doc today and he is 25" and 13lb 8oz. He is small, but also very active and not eating much during the days. He has been sleeping in his crib some during the day, but he doesn't sleep very long as he is probably hungry. He ends up sleeping on me quite a lot. Hopefully when I can start some solid food, he will start sleeping more (like how things went with Liana).
