So last Thursday, Ainsley still wasn't crawling. However, much to my surprise, on Friday, Ainsley figured it out! She started finally going forward and getting place to place. This weekend she really got it down and is getting faster and faster.
She absolutely loves crawling, it's keeping her very occupied and entertained. She also gets really tired, but doesn't want to sleep not that she has this new skill. She's sleeping soundly right now, hopefully she'll stay that way for a little while longer. :)
