What is the best thing for diaper rash?

Clean, dry skin: Diaper rash can be best managed with very absorbent diapers that are not placed tightly and get changed soon after soiling. Hygiene is the most important way to avoid this rash. Do not use alcohol/perfumed wipes as they may overly dry the skin and irritate it. Allow your baby to air dry, the longer they can go without a diaper the better. Over the counter pure white petrolatum ointment may help.

Diaper rash: For diaper rash keep baby's skin clean & dry. Change diaper as soon as it's soiled or wet. For healing allow baby to go without diaper for periods of time so affected area can air out. Avoid tight diapers or airtight covers over diaper. Meds your Dr. might recommend include antifungal cream (for fungus), a steroid cream (for significant inflammation) or an antibiotic (for bacterial infection.)
