She just keeps on goin'.
Ruby is walking so much more. She's developed a little bit of an 'old man shuffle': tiny steps that allow her to get farther without falling. She used to take big, more typical steps, but couldn't seem to get more than 6-ish before losing her balance. Now she can (and routinely does) make it all of the way from one room to the next, sometimes stopping mid-walk to regain her balance, but never sitting down. She is learning to pick things up and carry them as she walks, and (on her own) she's learning to change direction as she walks.
Ruby will stand on uneven surfaces all of the time. Usually it's her trampoline, but she did it on Maddux's bed the other night too. (yay) And she doesn't try to slide her way down the stairs, head-first, anymore. She has been turning herself around to 'crawl' down backwards for a few weeks.
