(More catch-up!) Taken September 5.
At this point Andy had been tummy-crawling all over the place for quite a while, but was just starting to get up on his knees. He'd push up and then rock back and forth, and drop his head down and look at his knees. It was like he knew what the next step was but just hadn't quite gotten all the parts coordinated.
Compare Kate at 36 weeks (these are cute).
