|I would think that you could feel an actual scab, since it would usually have a sort of an edge to it. When my DS had a rash from sitting in acidic poop, the apots that were rashy got kind of dry and rough as they were healing. I tended to put barrier cream on them as they were healing. If you are looking for something you can get in the regular store, I have used Boudreaux's Butt Paste (with fleece liners, and sparingly, so I am not positive how it would be for straight contact, but have read others mention it as something they use) and some people use Desitin Creamy, which doesn't have the fish oils that the regular stuff does. I never ordered anything special for diaper creams, just figured that used sparingly and infrequently, just about anything is probably going to be okay.
