Diaper Rash: Causes, Treatment & Prevention

Diaper rash is one of the most common — and most uncomfortable — baby skin issues. Almost every baby gets it at some point. The good news: most cases clear up quickly with simple, gentle care at home. Here’s what causes it, how to treat it, and how to keep it from coming back.

What Causes Diaper Rash?

• Wetness & friction — prolonged contact with a wet or soiled diaper is the #1 cause.
• Irritation from stool, fragranced wipes, or new products.
• Chafing from a too-tight diaper.
• New foods that change stool acidity (common when starting solids).
• Yeast (candida) — a bright-red, bordered rash in the skin folds that doesn’t respond to regular creams.
• Antibiotics (for baby or a nursing mom) can trigger rashes.

How to Treat Diaper Rash (The A-B-C-D-E Method)

• A — Air: give plenty of diaper-free time so skin can dry and breathe.
• B — Barrier: apply a thick layer of a non-toxic zinc-oxide diaper cream at each change to protect the skin.
• C — Clean & gentle: use warm water and a soft cloth or fragrance-free wipes; pat (don’t rub) dry.
• D — Diapers: change frequently and make sure the fit isn’t too tight; size up if needed.
• E — Easy on products: pause new wipes, soaps, or detergents that may be irritating.

Choosing a Safe Diaper Cream

Look for a simple zinc-oxide formula free of fragrance, parabens, and dyes. Many families prefer creams with soothing natural ingredients like calendula or shea butter. Browse our vetted non-toxic baby skincare for gentle options. If you cloth diaper, choose a cloth-safe cream so it doesn’t reduce absorbency.

Preventing the Next One

• Change diapers promptly — every 2–3 hours and right after poops.
• Let the area fully dry before re-diapering; consider a daily barrier cream if your baby is rash-prone.
• Use fragrance-free wipes or just water.
• Don’t over-tighten diapers; allow a little airflow.
• Wash cloth diapers in a fragrance-free, non-toxic detergent.

When to See the Doctor

• The rash doesn’t improve after 2–3 days of home care.
• It’s bright red and raised with smaller spots around the edges (possible yeast — needs an antifungal).
• There are blisters, open sores, pus, or it’s spreading.
• Your baby has a fever or seems unwell along with the rash.

Frequently Asked Questions

How long does diaper rash take to heal?

Most mild diaper rashes improve within 2–3 days with frequent changes, air time, and a zinc-oxide barrier cream. If it isn’t getting better in that window — or it looks like a yeast rash — check with your pediatrician.

What is the best cream for diaper rash?

A thick zinc-oxide barrier cream, free of fragrance and dyes, is the go-to for protecting and healing irritated skin. For prevention, a thin daily layer works well. For a suspected yeast rash, your doctor may recommend an antifungal cream instead.

Can wipes cause diaper rash?

Yes — fragranced or alcohol-based wipes can irritate sensitive baby skin. If your baby is prone to rashes, switch to fragrance-free wipes or simply use warm water and a soft cloth. See our non-toxic baby wipes guide.
