Dr. Amy Kim, a dermatologist and mother of two, has created Dr. Amy’s Daily 4 – the 4 steps you need to take each and every day to keep your baby’s skin healthy and soft.

The fourth step of the Daily 4 is Spotting and Soothing diaper rash. Almost every baby will have a case of diaper rash before the age of three. There is a range of diaper rash and it can show up quickly or gradually. Diaper rash causes include irritation, wet diapers left on too long, increased frequency of poops from a change in diet or antibiotic use, and diapers that are put on too tight. Typically diaper rash will appear as a bright red patch in the diaper-covered area. If this phase goes untreated, the diaper rash can progress and result in an overgrowth of yeast and culminate in a full-blown diaper rash with satellite red bumps and pustules.

To prevent diaper rash, apply a moisturizing ointment with most diaper changes to provide extra protection between baby skin and their pee and poop. Zinc oxide is the white stuff that you see in both sunscreens and diaper rash remedies since it acts as a physical blocker. Zinc oxide further protects the skin by acting as a physical barrier between your baby’s skin and the pee and poop elements. When diaper rash has set in, diaper rash treatment is a priority. You must increase the frequency of diaper changes and make sure that diapers are not too tight. You may also want to let your baby go diaperless for short periods of time while at home to let their bottoms breath. You can use a warm washcloth instead of a wipe as this can be less irritating and more soothing. If red bumps appear, you can apply an anti-yeast cream like over-the-counter Lotrimin AD mixed with diaper rash ointment 2 to 3 times a day. After 2 to 3 days, if symptoms have not improved, see your pediatrician or dermatologist for diaper rash treatment.
