I used cloth diapers to great effect with my two kids. We'd use disposable ones when going out, but for around the house (and at daycare, bless them!) we were able to use cloth. I think we saved a pile of money, and yes, they were both trained pretty early.

Nobody wants them, even free... I guess I'll just throw them all out eventually, I've offered to new parents and they're all horrified by the concept
