I love the story of Jesus Christ blessing the children in the Book of Mormon, and Lesson 6 is a great opportunity to have the children read (with help!) the scripture story. Here's a PDF coloring page that goes along with the lesson: Heavenly Father and Jesus Love Me Coloring Page
Jesus Loves Me from the LDS.org Children's Lesson Helps. (They've recently updated it with resources for Lessons 1-9.)
Finally, I have been singing the song, "My Heavenly Father Loves Me" all week, and now I know why! You can teach/sing this song with these beautiful cards from Amy Snyder or these cute illustrations from Pat Kelsey Graham.
