My doctor told me a of a concoction that worked for my little ones. I have 10 month old twins and one of them had a bad rash last week. It's a paste made from Balmex, Mylanta (the acid reflux liquid), Lotrimin AF (antifungal cream), and Cortaid 1% (hydrocortisone). It worked beautifully. If that still doesn't work, take him to the doctor and they can prescribe Vusion. That works like a charm, but try the paste first.
