Inurable Diaper Rash?

Christine

My little girl has had a patchy red rash on her tush since she came home from the hospital. So about 4/5 weeks.

I've slathered diaper rash creams on her (aquaphor, desitin, calmoseptime, butt paste).

Went to the pediatrician and he gave us an Rx for a yeast infection. 7 days later, that hasn't worked at all...it actually looks worse.

Anyone else going through something similar?
