What is the gift Mother Courage gave Eilif that appears in scene 2?

I am not sure what you mean here Foefoe. Could you provide maybe a quote or a link that I can use to answer your question? Or a scene maybe?

This will really help me! I think I can provide a link, based on your question:

Is it the major theme of the play?
