Congratulations on your new arrival! Now that your sweet bundle of joy is here, you are likely spending a lot of time on diaper duty. However, even with the best care, diaper rash can still happen, and it is important to know that this is not a reflection of your parenting. Diaper rashes are among the most common skin conditions in babies and infants, and it is something nearly every parent will encounter at some point. As a pediatric dermatologist, I am here to provide you with helpful tips to prevent and treat diaper rash so your baby’s delicate skin stays comfortable and healthy.

What is diaper rash?

“Diaper rash” is an umbrella term that refers to any rash that develops in the area covered by the diaper. The most common cause is irritant dermatitis, which occurs when your baby’s skin comes into contact with moisture, urine, and stool for prolonged periods. While it can be uncomfortable for your little one, diaper rash is typically a mild condition that can be managed with proper care. The following tips can help to both prevent and treat diaper rash.

Keep the area dry

  • Use absorbent diapers: Disposable diapers with absorbent gels can keep your baby’s skin drier than cloth diapers. 
  • “Air time”: While it’s not always practical, giving your baby some diaper-free time can help their skin dry out and recover. Even short periods of air exposure after diaper changes can make a big difference.
  • Change diapers frequently: Aim to change your baby’s diaper as soon as it is soiled. This is especially important in the early days when your baby may need a diaper change as often as every 2 hours.

Create a barrier

  • Use a barrier cream: Applying a thick layer of a barrier or cream such as zinc oxide at each diaper change can help protect your baby’s skin from urine and stool. Think of it like frosting on a cake — apply generously!
  • Don’t over-clean: When changing your baby, gently wipe off the top layer of barrier cream, but you don’t need to remove all of it with each change. At bath time, a gentle cleanser can help clean the area without irritating it.

Use gentle wipes

  • When wiping, make sure you are using fragrance-free, alcohol-free baby wipes. For extra caution, you might also use a soft, dry cloth moistened with warm water to cleanse the area.

When to call the doctor

In most cases, diaper rashes improve with proper care. However, you should contact your child’s doctor if:

  • The rash does not improve despite gentle care
  • You notice pus-filled bumps or open sores
  • Your baby seems uncomfortable or in pain during diaper changes

By following these simple steps, you can help prevent and manage diaper rash, ensuring your baby’s skin stays happy and healthy. Remember, diaper rash is common, and with a little care, it can be easily treated!
