What's better than free babysitting?

My friend Sarah, with the help of her daughter Ella, sat for Isaac when I went to my prenatal appointment on Thursday. She and I are in this groove where we swap babysitting for each other.

So what could possibly be better than free babysitting? How about a free babysitter who takes pictures of your adorable boy in action?
