The bubble moves

Brooks started taking his first steps about 3 weeks ago. Each day he gets a little more brave and lets go on his own to get to what he wants. Most often he lets go when he shouldn't so he just lunges for the nearest stable object and if I'm around he'll even just topple backwards like a straight log - kinda like the trust fall just to make sure I am alert. He doesn't quite understand the balance thing yet and how that plays into walking but he'll get there. Nonetheless, he seems to be very proud of the progress he has made and we are too!
Any predictions? Another month before he is fully mobile or do you think he'll try to show off at his first birthday party next Sunday?
And again...
