HOME CARE ADVICE FOR DIAPER RASH
Change Frequently: Change diapers frequently to prevent skin contact with stool. It may be necessary to get up once during the night to change the diaper.
- Rinse with Warm Water:
- Rinse the baby's skin with lots of warm water during each diaper change.
- Wash with a mild soap (such as Dove) only after stools. (Reason: Frequent use of soap can interfere with healing).
- Avoid diaper wipes. (Reason: They leave a film of bacteria on the skin).
- Increase Air Exposure:
- Expose the bottom to air as much as possible.
- Attach the diaper loosely at the waist to help with air circulation.
- When napping, take the diaper off and lay your child on a towel. (Reason: Dryness reduces the risk of yeast infections).
- Anti-Yeast Cream: If the rash is bright red or does not respond to 3 days of warm water cleansing and air exposure, suspect a yeast infection. Apply Lotrimin cream (no prescription needed) 3 times per day.
- Raw Skin: If the bottom is very raw, soak in warm water for 10 minutes 3 times per day. Add 2 tablespoons (30 ml) of baking soda to the tub of warm water. Then apply Lotrimin cream.
- Sore or Scab on End of the Penis: Apply an antibiotic ointment such as Polysporin (no prescription needed) 3 times per day. (Reason: a bacterial infection that can cause painful urination).
- Diarrhea Rash: If your child has diarrhea and a severe rash around the anus, use a protective ointment (barrier ointment) such as petroleum jelly, A&D or Desitin. Otherwise these are not needed. Caution: Wash off the skin before applying.
- Expected Course: With proper treatment these rashes are usually better in 3 days. If they do not respond, a yeast infection has probably occurred.
- Call Your Doctor If:
- Rash isn't much better in 3 days on treatment for yeast
- Your child becomes worse
