As a pediatrician with over 15 years of experience, I’ve had countless conversations with concerned parents about diaper rash. It’s one of the most common skin conditions in infancy—and understandably so. Understanding the different types and their treatments can help you care for your baby with confidence.
When Something Is Touching the Skin
One of the most frequent causes of diaper rash is simple contact. Stool contains digestive enzymes that are great for breaking down food—but unfortunately, they also break down skin. This is especially true during bouts of diarrhea.
A helpful trick: a 1:1 mixture of an emollient and an antacid can soothe this type of rash. The emollient moisturizes and protects, while the antacid neutralizes the enzymes.
For contact dermatitis, I recommend:
- 1% Hydrocortisone cream twice daily for 2-3 days
- A thick layer of zinc oxide ointment with every diaper change—thick enough that you can’t see the skin underneath.
When Something Is Growing on the Skin
Babies have fewer natural skin microbes than adults, which leaves room for yeast (fungus) to grow. One common culprit is Candida albicans, which often appears as redness in the skin folds, surrounded by small red “satellite” spots.
This type of rash requires an antifungal cream. It’s important to get the diagnosis right—using hydrocortisone alone can actually make a yeast rash worse.
When Bacteria Invade the Skin
Sometimes, diaper rash opens the door for bacterial infections like impetigo, cellulitis, or even abscesses. Signs include:
- Intense redness
- Swelling or tenderness
- Hardness under the skin
- Drainage or scabbing
These infections need prompt treatment with topical or oral antibiotics.
Prevention: Your Best Tool
- Avoid known irritants like harsh soaps or fragrances.
- Use a barrier ointment (like zinc oxide or petroleum jelly) with every diaper change.
- Change diapers promptly after bowel movements.
- Air dry skin for 5-10 minutes.
