It's still not crawling, but rather, advanced butt-scootching. See, Miss T. really, really likes sitting up. She conquered the tummy time conspiracy by figuring out how to push herself up with her hands and flip her legs forward so that she's sitting up.
But now she can move a non-trivial distance in the direction of her choice, scootch scootch scootch, even when holding a toy in each hand. We are babyproofing like mad. Cabinet locks are done; it's safety gates next.
"How long before she gets to the kitchen worktable?"
"Sometime tomorrow. [pause, watches] Maybe tonight. [pause] Maybe in five minutes."
"I say forty-five seconds."
"You're right." [CRASH as pan lid taken from the worktable's low shelf hits floor.]
Plus we got the same lead results, a level of 4, as Sophia did at the nine-month checkup—except our baby wasn't mobile yet. Which has led (ha!) to a lot of paralyzing worry, and a little throwing of toys into the dishwasher, and a little home testing, but that's it so far.
