Diaper Free Babies?

I just came across this book online and began to look in to the phenomenon that is "diaper free babies". I'll have to get this book to give you the full scoop but from what I understand babies have a thing called elimination communication which lets you know when they need to go to the bathroom, you take them to the toilet and they eliminate, making the use of diapers...well useless! Sounds great doesn't it? I'll investigate further and let you know what I find!
