Claire's sleep has been weird...as if things in her are...changing. And her crawling on her hands/knees has kind of morphed into "crawling" on her hands and feet...it's weird looking. And, she's starting to stand, without any assistance, for longer (and more frequent) periods of time.
Her speech patterns are changing and it sounds like she's trying to say what's on the innermost part of her heart, the things she really thinks about the world...important and menial.
Basically, *crying* she's becoming a little girl...and leaving her little baby-self behind! If you don't believe me, just look!
