Not to be counted out, Mazie Bell sat herself up today and has done it countless times since.
She is enjoying being able to move over to a toy and then stop, sit up, and spend some time with it.
I watched her come down the hall. She'd belly crawl about two feet and then sit up. Then she'd crawl a few more feet, stop, and sit up. It is like the light has been switched. The girl has got it now.
