No more wipes. Use damp paper towels, dampened only with water. When you bathe him, use only clean water. Don't add soap to the water. He doesn't need more than that for cleaning, and the soap can be harsh on damaged skin. After a bath let his skin air dry as much as possible.
If you want to take some of the acidity out of the rash, you can soothe it with plain Phillip's milk of magnesia. When that dries, apply Lotriman cream .1%. Top that with Balmex diaper rash cream.
Be sure to change as soon as he wets or poops as long as he has the rash like this. The fact that it's bleeding tells me that you should call the pediatrician. The advice I gave you is assuming he has a yeast infection from the poopy diapers, but you really should make absolute certain with the doctor visually.
EDIT: By the way, if it's a yeast rash like I suspect do NOT NOT NOT use cornstarch baby powder or any powder at all. It will feed the yeast and make the rash WORSE.
