Cael can now balance pretty well. He generally needs at least one hand on something to keep from toppling, but he can hang in there a long time. Without any support he can manage about five seconds before falling (on a good try).
Also, if you hold onto his hands he'll take big, prancing high-steps and lead you where he wants to go (usually to the room where Ryan is trying to study).
He's most enthralled with his new ability to stand with his face smooshed against the mirror or a window and slobber all over. I think he's in a competition with his own reflection over who can produce the most spit.
So far, it's a tie. I'll let you know who wins.
