I hate to have such a gross sounding topic, I apologize in advance.
Yesterday we noticed a handful of white pimples on B's butt, near the hole.
I googled diaper rash, and that seems to be appear more over the cheeks and is a lot redder than what I see. I just see white pimples, much like adult whiteheads.

Is this still diaper rash?
If it doesn't clear up in a day or two I will call the pediatrician, but it doesnt seem to be causing any pain.
