Diaper rash, or diaper dermatitis, is a very common problem. Half of all babies under one year old will get it at some point [1]. Though it’s frustrating, it’s usually simple to fix.

What does diaper rash look like?

Diaper rash and redness are caused by moisture, urine, or feces. Less frequently, due to rubbing. In some cases, it is because of increased skin sensitivity [1]. The first irritations typically appear between the buttocks, so parents may not notice them right away. The redness will spread over time, making the rash visible [2]. The baby may also become agitated and whiney. 

Which diapers offer the best protection against diaper rash?

The more absorbent the diaper, the lower the risk of dermatitis [1, 2]. If you use cloth (reusable) diapers, you should change them frequently. All poopy diapers must be changed immediately; even the most absorbent diaper should not be left on. 

Studies have shown [2] that diaper rash is more likely to develop in babies who sleep in the same diaper all night. So it’s best to change your baby's diaper at least once per night.

There is no diaper brand that is ideal for everyone. Try a few different brands to see which one is best for you and your baby. 

Do you need a diaper cream?

Yes. It is a barrier that prevents caustic substances in feces and urine from irritating your baby's delicate skin [1].

Is it better to wash or use wipes to change a diaper?

It doesn't matter. If you wash, do so with warm water and a baby body wash with a pH less than 4.5. Wipes should be free of alcohol and perfume, with a pH less than 4.5 [2].

How to treat diaper rash?

Proper care and hygiene are sufficient to clear the redness in two to three days. Healing creams can be applied to the skin, and leaving the baby naked may also be beneficial. Allow baby to lie down on a clean blanket for 10-20 minutes.

If the diaper rash becomes infected, see your pediatrician [1]. 

In what other situations do you need to see a doctor?

Consult your pediatrician if:

  • hygiene and home treatment do not provide relief after three days

  • diaper rash is swollen, wet, covered with bubbles or cracks

  • the child cries when peeing or pooping

  • the baby has a fever.

Frequently asked questions

With proper care and hygiene, diaper rash typically clears up in 2-3 days. If it persists longer than 3 days despite treatment, consult your pediatrician.

Any barrier cream that creates a protective layer between baby's skin and moisture works well. Look for creams specifically designed for diaper area protection and apply with each diaper change.

Both are fine if used properly. Use warm water with gentle baby wash (pH under 4.5) or alcohol-free, fragrance-free wipes with pH under 4.5.

Contact your pediatrician if the rash doesn't improve after 3 days, appears infected with swelling or blisters, or if baby cries when urinating or has fever.

While not always preventable, frequent diaper changes, using absorbent diapers, applying barrier cream, and keeping the area clean significantly reduce the risk.
