Get a package of cotton candy (I found some at Wal-mart).  Show the girls the cotton candy...pick off a piece and roll it in a ball.  Hold up the original cotton candy to the ball you just created and tell them that we are a lot like the cotton candy.  Explain that cotton candy is cotton candy, whether in a ball or in its light and fluffy form.  We are all God's children and He loves us all, regardless of how our bodies are formed.  We need to be compassionate, look deep, and be sensitive to the feelings of others.

In one ward we were in, we had quite a few children who had different learning disabilities.  For a teacher inservice, I handed one of the teachers a Japanese Book of Mormon and asked her to read it out loud for everyone.  She could not and looked rather flustered.  I then began to read from the book for them and then turned to someone and asked them a question in Japanese.  We then talked about the feeling of frustration some of our children may have, how to help them process the information we are giving them and how to help them feel more comfortable. Sometimes they may not be able to hear us or understand us as well, sometimes they may not be able to read as well, …  I thought it worked quite well as an introduction. (Dona Braswell)
