4 legs good, 2 legs good

Both boys walked today for the first time. They've taken a few stutter-steps here and there over the past few weeks, but today, egged on by Impy's lady friend (AKA his PT), they took three steps each.

It was weirder than I expected. It seems to me that crawling was a more life-changing milestone, since it meant mobility and all the life changes that entails. Walking is just crawling with a couple fewer limbs, isn't it? Yet walking is generally considered more of a big deal. Seeing them walk affected me, but I'm not quite sure how or why. Must ponder.
