Carly finally sat up on her own today! There are two great things about this development, 1) it's a significant milestone and 2) she will no longer need to cry in frustration for our help to sit. (Now, I am sure, it will be crying to stand.)
In the past I have tried several times to post videos with no success. Tonight I finally accomplished it. I posted a short video. So, for your viewing pleasure . . . Carly's latest triumph!
