Well, I looked into what was in Calamine lotion. 8% zinc oxide and 8% Calamine. Diaper rash ointment has 40% Zinc oxide, so I tried that. It appears to be helping, for now. Then again, so did all the other oinmnents, but this seems to be drying it up as well as moisturizing it, so I have hope that this is going to work. Thanks for all the suggestions.
