Treating a diaper rash, or red butt, on a baby is usually simple but in some cases the rash may be persistent. Always seek medical assistance if the rash is severe, lasts more than a few days or is recurring.
Step 1
Run a bath for your baby as you normally would but toss in a handful of oatmeal or 1/4 cup of baking soda. Test the water before letting your baby into the water. Use your elbow and not your hand for a more accurate temperature.
Step 2
Soak your baby in the tub for 15 to 20 minutes, then remove him.
Step 3
Pat dry with a clean towel. Allow him to play for as long as possible without a diaper on. Protect the surface he is playing on with a few extra towels.
Step 4
Place a pea-sized amount of medicated ointment onto a cotton swab and apply directly to the red area. If more ointment is needed, use a new cotton swab to prevent contaminating the tube.
Step 5
Replace your baby's diaper.
Step 6
Change the diaper more frequently than normal and attempt to leave him naked after every changing if possible. Be sure to dry him thoroughly at each changing.
Step 7
Reapply the ointment as needed for one to two days. If the rash has not cleared by this time, consult a health care professional. The rash may be the result of a bacterial or fungal infection. These infections can be treated with over-the-counter ointments, such as zinc oxide, lanolin and even an anti-fungal cream.
Tips and Warnings
- Zinc oxide containing ointments can be highly effective but some children may be sensitive to the ingredients. Eliminate fragrances including diaper wipes and laundry or bath soaps. A sensitivity to dyes, fragrance and any other ingredient in personal care products, including diapers, can cause recurring rashes in babies. Assess your baby's diet. If a new food has been introduced recently, a red bottom may be an indicator of a food sensitivity. This doesn't necessarily mean a food allergy but it should be discussed with a pediatrician.
- If the diaper rash also comes with blisters, bleeding, unusual markings, spreads or causes significant crying, visit your baby's pediatrician right away for treatment.
