Would you give her the bear? (Details inside.)

I am finishing up a stint working in a class of students with moderate to severe mental disabilities. For a lesson I taught this class I brought in a stuffed teddy bear from my house. One of the girls in the class loved this bear. She hugged him through the entire lesson, asked me if I could leave him at school, and has had him with her all day every day since I brought that bear to school. This bear is fairly average at first sight, but it is very special to me because my son sewed it in his home economics class last year. I have talked to my son about this girl and how much she loves Teddy (she named him). He says that he would be happy to have the bear go to someone who loves it so much. I am torn about giving up something that my son sewed – especially since it is more than likely the only one he will ever make. I want to give her the bear, but I am struggling to part with it. What would you do?
