On my last one I used A+D baby ointment at night, then the non-smelly Smooth Baby Butt Lotion the next day (it's seriously called Baby Butt the brand is Bordeaux, I think.) Mine was essentially a diaper rash, just a lot of red, red skin. I did a lot of searching here on cures, and there are so many options. I'm doing my best to prevent them now!
