Both mine kids who are 3 and age 2
could not use over the counter medicine.
The Dr prescribed a special Diaper rash cream,
and its called Happy Hinny.
Its the best, once you use it, usually
within a day its almost cleared up.
Girls have more of a problem,
especially if they are having diarrea.
I couldn't watch there suffer.
So definately call the Dr and both
Dr here where we live and were we use to live
didn't hesiate to give them something stronger.
Its a thicker cream and is does last a long time,
and it works so great.
The name says it all...Happy Hinny
