What's a good audition song for the Baker's Wife in Into the Woods?

My school is putting on a production of "Into the Woods" (Sondheim) this winter, and I want to be the Baker's Wife. I'm very experienced in theatre and choral singing, so I think I have a good shot at getting the lead if I nail the perfect audition song. My range goes from Eb3 to D6 (counting middle C as C4). Any suggestions, or other tips for the audition? Thanks so much!
