Milestones...do I like them?

Well, Eowyn has found her feet, and likes to grab her toes while she's being changed. She is grabbing and holding on to things much more, and with greater control. Yesterday she was in a lounging position, and pulled herself to a sitting position...she promptly flopped to the side, but still, she pulled herself up! She seemed to realize this was a great accomplishment and is happy to try again whenever given the chance. She's not crawling, but she can push herself up from a flat on her belly position, with her hands, but her knees don't quite make it...she does seem to realize that is what needs to happen next. I'm not sure I like this...everyone said that they grow up very fast, and I knew they were probably right...but wow!
