Cost Diapering

I'm sold on the sustainability, environmental and potential cost savings of cost diapering. I haven't been able to find anything that talks about potential health benefits for the child using disposable diapers with the chemicals and dyes that they put in them. Do you have any compelling resources that you and your wife use when making the cost diaper decision? The biggest argument in favor of safety for the baby would apply if the baby is a boy because cloth diapers are cooler than plastic diapers.
