As a parent, seeing a red, angry rash on your baby’s bottom can be alarming. While most diaper rashes are caused by irritation from wet or soiled diapers, sometimes the culprit is a yeast infection. Knowing how to tell the difference between a yeast diaper rash vs regular diaper rash is key to getting your little one the right treatment.

In this article, we’ll cover everything you need to know about yeast diaper rash symptomshow to treat yeast diaper rash, and tips for preventing yeast diaper rash from recurring. Armed with this knowledge, you can help soothe your baby’s sore bottom and keep that soft skin healthy.

What Is a Yeast Diaper Rash?

Yeast diaper rash, also called candidal dermatitis, is caused by an overgrowth of Candida yeast[1]. This fungus thrives in warm, moist environments like your baby’s diaper area. While Candida is normally present on the skin, certain factors can cause it to grow out of control, leading to an uncomfortable rash.

Babies are especially prone to yeast infections because their immune systems are still developing. Antibiotics, which can disrupt the balance of bacteria and yeast, are another common trigger[2]. If your baby has recently taken antibiotics or if you are breastfeeding and have taken them yourself, be on the lookout for symptoms of a yeast infection.

Yeast Diaper Rash Symptoms

So what does yeast diaper rash look like? Here are the key signs to watch for:

  • bright red rash with clearly defined borders[3]
  • Rash is concentrated in the folds of the skin
  • Scaly, peeling skin or small red bumps (satellite lesions) surrounding the main rash area
  • Rash does not improve with regular diaper rash treatments

In contrast, a regular diaper rash tends to be pink rather than bright red. It covers a larger area and isn’t focused in the skin creases. The skin may look irritated and puffy but not scaly or bumpy.

If your baby’s rash looks suspicious for yeast and doesn’t get better with 2-3 days of regular diaper rash cream, it’s time to treat for a yeast infection.

How to Treat Yeast Diaper Rash

The good news is that yeast diaper rash is very treatable, although it may take a little longer to clear up than a regular diaper rash. Your pediatrician can recommend an antifungal cream specifically designed to tackle yeast[4]. Look for over-the-counter clotrimazole, nystatin, or miconazole creams, or ask your doctor for a prescription strength option.

To use the cream:

  1. Gently clean your baby’s bottom with warm water and pat dry.
  2. Apply a thin layer of antifungal cream to the entire rash area with each diaper change.
  3. Use the cream for as long as your pediatrician recommends, even if the rash starts to look better. Stopping too soon can lead to a recurrence.

In addition to using an antifungal, practice these tips to help clear the rash:

  • Change diapers frequently to keep the area dry
  • Use a mild, fragrance-free soap and avoid baby wipes while the rash heals
  • Give your baby’s bottom time to air out with diaper-free time on a towel
  • Consider soothing baths with baking soda to help relieve itching and burning[5]

If the rash doesn’t start to improve within a few days of treatment, spreads to other areas of the body, or if your baby develops a fever, see your pediatrician. A stubborn rash may require a prescription-strength medication.

Preventing Yeast Diaper Rash

Once you’ve cleared up a yeast infection, taking steps to prevent it from recurring is important. These yeast diaper rash home remedies and prevention strategies can help keep your baby’s bottom rash-free:

Keep It Clean and Dry

Yeast thrives in a moist environment, so keeping your baby’s diaper area as dry as possible is key. Change diapers frequently, especially after bowel movements. Gently pat the skin dry with a soft towel before putting on a fresh diaper. When possible, let your baby go without a diaper for short periods to allow the skin to dry completely.

Use the Right Products

Choose mild, fragrance-free wipes or a soft washcloth and water to clean your baby during changes. Avoid wipes with alcohol or fragrance, which can be irritating. Look for a diaper cream with zinc oxide to create a protective barrier on the skin[6]. Petroleum jelly can also help protect the skin from moisture.

Consider Probiotics

Studies suggest that probiotics, beneficial bacteria, may help prevent diaper rash[7]. Probiotics can help maintain a healthy balance of bacteria and yeast on the skin. Talk to your pediatrician about giving your baby a probiotic supplement or look for diaper creams that contain probiotics.

Manage Diarrhea

Diarrhea can be a major trigger for diaper rash because it increases moisture and irritants in the diaper area. If your baby has diarrhea, be extra diligent about diaper changes and apply a thick layer of protective cream. Call your pediatrician if the diarrhea lasts more than a day or two, as this can lead to dehydration.

Address Antibiotic Use

If your baby needs to take antibiotics, ask your pediatrician about giving a probiotic as well to help prevent yeast overgrowth. If you are breastfeeding and need to take antibiotics yourself, you may need to use an antifungal cream on your nipples to prevent spreading yeast to your baby[8].

Yeast Diaper Rash vs Other Types of Rash

Not every diaper rash is caused by yeast. Bacterial diaper rash, for example, may have some similar symptoms but requires different treatment. Here’s how to tell the difference between a few common types of diaper rash:

Type of RashAppearanceLocationTreatment
YeastBright red, scaly bordersSkin foldsAntifungal cream
BacterialRed, shiny, pus-filled bumpsThroughout diaper areaAntibacterial cream
IrritantPink, puffyThroughout diaper areaFrequent changes, protective cream
EczemaRed, scaly, itchy patchesMay extend beyond diaper areaMoisturizer, steroid cream

If you’re unsure what type of rash your baby has, play it safe and call your pediatrician. They can diagnose the rash and recommend the appropriate treatment.

When to See a Doctor

While most diaper rashes can be treated at home, there are times when you should seek medical advice. Call your pediatrician if:

  • The rash doesn’t start to improve after a few days of home treatment
  • The rash spreads to other areas of the body
  • Your baby develops a fever
  • The rash is extremely painful or bleeds
  • Your baby is less than 6 weeks old

Your pediatrician can determine if the rash is caused by yeast, bacteria, or another issue and prescribe the appropriate medication. They can also rule out more serious conditions like psoriasis or a skin infection.

The Bottom Line

Dealing with yeast diaper rash can be frustrating, but with the right treatment and prevention strategies, you can help your baby’s bottom heal. Remember, always consult with your pediatrician if you have concerns about your baby’s rash or overall health. With a little TLC and the right approach, that soft, smooth baby skin will be back in no time!

How long does yeast diaper rash last?

With proper treatment, yeast diaper rash should start to improve within a few days. However, it may take a week or more for the rash to completely clear up.

Can yeast diaper rash spread to other areas of the body?

Yes, yeast can spread to other warm, moist areas like the folds of the neck or armpits. Treat these areas with antifungal cream as well and wash your hands thoroughly after touching the rash.

Can breastfed babies get yeast diaper rash?

Yes, breastfed babies can still get yeast diaper rash. Yeast can pass back and forth between mom’s nipples and baby’s mouth and diaper area. If you are breastfeeding, be sure to treat your nipples with antifungal cream as well.

Can cloth diapers cause yeast diaper rash?

Cloth diapers can be more likely to cause yeast diaper rash if they are not changed frequently enough or properly cleaned. If using cloth diapers, be sure to change them every 2 hours and wash in hot water with a mild detergent.

When can I start using diaper rash cream again after treating a yeast infection?

Wait until the yeast infection has completely cleared before going back to your regular diaper rash prevention routine. Continue to use the antifungal cream for a few days after the rash is gone to prevent it from returning.
