It was the funniest thing. Yesterday Avery just leaned forward and crawled like she's been doing it for months. No rocking or wobbling, just straight out hands and knees crawling. She never even belly crawled or scooted! I swear this kid was just holding out on us this whole time :P
Of course, she still only uses it to get to something she can pull up and cruise on - but hey, it's progress right?
