Constant pooping, bad diaper rash help!

Miranda

EBF 12 day old baby boy is constantly pooping which Dr said was normal, but now he has diaper rash so bad it's almost about to bleed. We switched to water wipes and have been using the boudreaux butt paste and a&d switching between changes. Don't know what else to do to make it better. Anyone else have any suggestions or things they have done that helped.
