He is working on crawling by getting his knees under himself, getting his butt into the air, and moving his legs. But, he needs to figure out he also has to get his upper body off the ground. I'm not particularly in a hurry for him to figure this out though, as I like my immobile little man!
His personality is coming out more and more. He's just such a happy and fun baby 90% of the time, but can become upset at the drop of a hat. He is really in tune with the emotions of others, especially other babies. If he hears/sees another baby cry, he'll get upset. He really likes most people, though it seems he plays strange with people with curly hair and/or thick glasses for some reason!
