(Hm, random thought... walking_angel is also an Amy... how appropriate for this entry!)
Yesterday, I saw for the first time Amy walking, of her own volition, more than one or two steps to a goal other than a parent's outstretched arms. She was definitely toddling around a little, even without anything in her hands to distract her! And she also turned around on the spot, slowly.
She'd still sometimes drop to her knees and crawl the rest of the way, but she was definitely walking several times. Whee!
