I've been working on that update, but just can't seem to get it finished. I'll keep working on it.
Last Saturday, when I woke The Bean up, I brought him downstairs and sat him down on the floor. Every time I tried to get him to sit he would immediately flop over, but not this time. Since that day, Max can officially sit.
He's been working on his crawling and has a pretty serious "army crawl" down. We had expected he would be crawling by now, given the rate that he was developing, but we expect a full crawl any day now (I'm sure it'll happen on the weekend when I'm watching him). I'll make sure to let you know when it happens.
