Triple Paste...definitely one of the better pieces of advice I got from one of my sisters. That stuff was awesome, and it didn't stink like some of the other creams did.
Here is some info on it, if you are interested!
Creams for severe diaper rash:
Triple Paste. This "super cream" is great for severe rashes. It is a combination of petrolatum, zinc oxide, lanolin, beeswax, and cornstarch. This cream may be difficult to find, but most pharmacies can order it from Summers Laboratories (1-800- 533-SKIN).
