Sitting up

Levi has been working really hard on his sitting up. I think we can say that he has accomplished this milestone. I'm not really sure how long he must remain in seated position to count as "sitting up", so I am not sure if we count Christmas Eve, Day, or the day after. He still does not remain in the seated position for minutes on end, but he can for several minutes - especially when he's driving his "car" that he got for Christmas. I'll add pictures later.
