My son, Corbin, did his first bit of real walking, this Morning. He's been doing some forward falls while taking a couple of steps on the way down, before Today, but Today is the first day that he's moved his feet forward to maintain his balance. He still falls within 5 seconds of starting, if we don't catch him, but he does, at least, get the idea of moving his feet to maintain his balance. Now, he just needs practice.
He is, now, officially a toddler.
