Here are a couple of videos of Sarah. The first is her laughing. She just started so I know it doesn't sound like much, but it is so precious. :-)
This next video is of Sarah finally reaching up and batting at the toys above her. We've been coaching her into batting at them for a week or so now, and a few days ago she finally reached up and started getting into it! I love that she can "play" with a toy now, it's so cute! AND, Emily is pretty impressed with it too. I think she's happy to see her do something that she can relate to.
