If you (like me) have never had to worry about where your child's next diaper, of all things, is going to come from, I think you will be surprised to know how many people face this problem every day. Michelle Sharpe, a music and early childhood intervention therapist with a background in opera, is doing something about this need, through her charity diapercircle.org. Our conversation ranges from how Michelle got into the charity biz in the first place to practical stuff every parent needs to know. Take a listen, you'll be glad you did!
