REALLY BAD yeast diaper rash... advice??

My daughter has had a BAD diaper rash for about a week now.. we've tried Boudreauxs, A&D, Triple Paste, Aquaphor, Vaseline, antifungal cream.. and a few others .. nothing has worked. We've even combined one with another and tried that route. We took her to doc today and all they told us was to stop giving her milk (she's 16 months and has been on cow's milk for 4 months and never had a rash til now?? .. and to use OTC antifungal cream.) ,, so I bought some more, put it on her without any other cream, and checked 20min later and she was peeling? Is this normal??
