Prayer for a Child by Rachel Field
Our sweet little girl loves this book! We picked it up at the library, of course, but are seriously considering it as a little Easter present for her because it's so adorable. It's a comforting little bedtime prayer. First Daughter will "read" it to us, jabbering away at each page before turning to the next. I think her favorite page of all is the one full of little children (as we pray for all the kids in the world).
It was one of the recommended titles in Honey for a Child's Heart and First Daughter's first real love of the ones we've tried so far.
