  • Diaper-wearing age group (birth to 3 years)

About This Topic


  • Mild rashes just have areas of pink dry skin.
  • Severe rashes have areas of red skin. In some areas, the skin may become raw or even bleed.
  • Yeast infections are bright red. The borders are very sharp. Small red bumps or even pimples may occur just beyond the border. Yeast rashes usually cover large areas.
  • Pink rashes are not painful, but raw ones can be very painful. This can lead crying and poor sleep.


  • Mild rashes can be caused by the drying effect of soaps.
  • Stool and urine left on skin can combine to make ammonia. Ammonia can cause a mild chemical burn.
  • Stools left on the skin can be very irritating because they contain bacteria. Urine alone has no germs in it and usually doesn't irritate the skin.
  • Rashes around the anus are common during bouts of diarrhea.
  • Rashes from irritants can get a secondary infection with yeast. Less commonly it can happen with bacteria.

Prevention of Recurrent Diaper Rash

  • Change diapers more often. Especially try to prevent skin contact with stool.
  • Rinse the baby's skin with lots of warm water when cleaning off stool. Don't depend on diaper wipes alone
  • Be sure to clean stool off all the skin folds. Cleaning the scrotum can be a challenge.

After Care Advice

  • Diaper rashes are very common in babies.
  • Often caused by not cleaning stool off the skin soon enough.
  • Here's some care advice that should help.
Change More Often:
  • Change diapers more often to prevent skin contact with stool.
  • You may want to get up once during the night to change the diaper. Do this until the rash is under control.
Rinse with Warm Water:
  • Rinse the baby's skin with lots of warm water after cleaning off stool.
  • Wash with a mild soap (such as Dove) only after stools. Reason: Using soap often can slow healing.
  • Do not depend on diaper wipes alone for removing stool. Reason: They leave a film of bacteria on the skin.
Leave the Bottom Open to Air:
  • Expose the bottom to air as much as possible.
  • Attach the diaper loosely at the waist to help with air exposure.
  • When napping, take the diaper off and lay your child on a towel. Reason: Dryness reduces the risk of yeast infections.
Anti-Yeast Cream:
  • Most diaper rashes respond to 3 days of warm water cleansing and air exposure. If you've tried this or the rash is bright red, suspect a yeast infection.
  • Buy an anti-yeast cream such as Lotrimin. No prescription is needed.
  • Use Lotrimin cream 2 times per day.
Raw Skin:
  • If the bottom is very raw, soak in warm water for 10 minutes. Add 2 tablespoons (30 ml) of baking soda to the tub of warm water.
  • Do this 2 times per day for a few days.
  • Then, put Lotrimin cream on the rash.
Sore or Scab on End of the Penis:
  • Use an antibiotic ointment such as Polysporin. No prescription is needed.
  • Do this 3 times per day.
  • Reason: The sore is a bacterial infection that can cause painful urination.
Diarrhea Rash:
  • If your child has diarrhea and an anal rash, use a protective ointment. Examples are petroleum jelly, A&D or Desitin.
  • This forms a barrier between the skin and the stool.
  • Otherwise, these generally are not needed.
  • Caution: Wash off the skin before putting the ointment on.
What to Expect:
  • With proper treatment, most diaper rashes are better in 3 days.
  • If the rash does not respond, a yeast infection has probably occurred. If so, start an anti-yeast cream.
Return to Child Care:
  • Diaper rashes cannot be spread to others. Yeast ones do not spread. Bacterial ones have a small risk until they are on an antibiotic ointment.
  • Your child does not need to miss any child care.
