Diaper rash?

my baby has bad diaper rash to the point that her doctor thinks i never put ointment on her but i use it after every change. any advice on what to do? im kind of poor so cheap solutions would be better unless you really think she needs something more expensive.

    Our doctor prescribed our daughter an antibacterial/antifungal ointment like prescription cortozone. It helped clear it right up. She got it so bad she was blistering and we were using ointment on her every change as well and changing her as often as we possibly could. You just apply it like rash cream after each change and then put rash cream on top. I would talk to your doctor about it.
