J.-- the same thing happened to my son, and my pediatrician said it looked like jock itch. How funny-- a little baby with jock itch! It was red and angry like you desribed, and very itchy for my son. The doctor said to put Lotrimin AF (antifungal) on it, and it worked like a charm. The doctor also told me that the best prevention for diaper rash is to put Vaseline on the bum at diaper changes and especially at bedtime. My son's skin is very sensitive, so on the rare occasions when he wakes up with a poop or has diarrhea, he'll get a rash, and if Boudreaux's Butt Paste doesn't work, I'll use the Lotrimin, and it soothes his skin. Hope this helps!
