dont know the magic mix but enven though I am usually not running to the dr for every little thing , my dd did get a yeast rash a few times and the dr gave me a special ointment. just wanted you to know.
ps: it wasnt any different looking as far as I remember, maybe more pimply??
I see corn starch and milk of magnesia is a popular remedy. (mixed equally into a paste)
mixture of Cornstarch, Milk of Magnesia, and Desitin (I cover dipes in fleece liner when using this non-CD friendly cream). (You can also use Balmex). Mix until it forms a creamy whip, then apply directly on the rash. I did this at each changing. Coat it well.
