Ellie is getting really mobile, and it is fun to watch! She army crawls all over. Last night she made it on to the wood floor and loved how quickly she could slide. She has also figured out how to get from her tummy to her hands and knees to a sitting position (and vice versa) so we knew it was time to lower her crib. I actually have to use the bar-thingie to lower the side now, and when I pull it back up it clicks, which will take E a little bit of time to get used to.
