L., I pray your baby will not go through what my son did when he was about 2. Everything we were doing to help him was worsening his rash, which became scary to look at! Turns out, he had a FUNGUS that is encouraged by diaper creams, and so much else that everyone (including doctor's offices by phone) were advising us to use.
Here's the only thing that immediately gave him relief AND cleared it up lightening quick: Loop Pharmacy (where my husband works) makes something called FANNIE CREAM or something like that. Bill McFarland (pharmacist/owner) created this stuff, and I swear it should be marketed better. It has zinc in it, which I think is the active healing ingredient. But sweetheart, it is AWESOME. I used it later for any other kind of skin problem that any of us has had and most of the time with great success.
Loop's number is ###-###-####.
Let me know what happens. Wanting comfort for your baby!
