I also like the Desitin, but you have to make sure you get the original. It's nasty and sticky, but as our Nurse Practitioner says, "That's the point." The creamy one just "melts" off. Make sure you dry the baby's bottom before you put the ointment on. Another tip from our NP, even the sensitive wipes can be too much with a rash. Get the soft paper towels (viva?) and get them wet. We have done this with both kids (super sensitive skin), and it works.
