Rebecca's pretty much mastered sitting by herself to the point where she is comfortable enough to start pulling her legs into to sit cross legged. A good month before Aiden was doing this. She loves to go in her exersaucer and if you are holding her while sitting then she likes to jump up and down on your legs. I figured that it was a matter of time before she is going to want to start stand up against things. She has been trying so hard to be mobile and to follow Aiden around so if it is easier for her to start cruising as opposed to crawling then so be it. And some pics of her fancy new trick.
