Sitting up!

When we were in Florida, Sebastian was sitting up really well, and Ben was sitting or standing only while he was being held. But Ben was very impressed with Sebastian, and on Christmas day, when the two of them were hanging out on the table, Andy took his supporting hands away and Ben sat up by himself! Since then he has gotten better and better at it, and now it's how he spends most of his awake time, sitting up with toys all around him, picking one up, chewing on it, waving it around, and putting it down somewhere else, and then picking up another one (if he doesn't already have one in each hand).
