Hi S.
i see that some people have already mentioned aquaphor, that is definently the way to fo, my twins are 2 and have such sensitive bums that they can only wear 1 type of diapers and only use wipes that are alcohol free, laytex free and bleach free, with leave only 2 types of wipes. anyhow, when they got ear infections last year the antibiotics gave them such a bad rash that my doc even gave me a prescription for butt cream, which worked ok, but honestly be careful, desitin stings my boys, and butt paste works, but stopped after about 8-10 months, aquaphor has 0 alcohol in it, and is petrolium based and is the only one out there that is, other than the one vasiline makes, and it doesn't have any medications in it. the zinc oxide in desitine and most others it what causes them to sting, so depending on how sensitive your little one is look for what each product has as its base ( the first few ingredient listed) petrolium works b/c like a&d it seals out weetness, and protects, but there are also healing medicines in aquaphor, that help heal (obviously) chapped, burned, blistered skin. it is definently worth the money.
