Diaper Rash FAQs
What causes diaper rash?
The most common cause is prolonged contact with wet or soiled diapers. Other causes include: friction, sensitive skin, new foods, antibiotics (in baby or breastfeeding mom), or yeast/bacterial infection.
How do I know if it's a yeast diaper rash?
Yeast rashes typically have: bright red color, defined edges, satellite spots (small red dots outside the main rash), and don't improve with regular diaper cream. They're often found in skin folds. Yeast rashes need antifungal treatment.
What's the best diaper cream?
For prevention, zinc oxide creams (like Desitin or Boudreaux's) work well. For mild rashes, petroleum jelly (Aquaphor, Vaseline) can help. For persistent rashes, thicker zinc oxide paste provides a stronger barrier. See our Aquaphor vs Desitin comparison.
When should I see a doctor for diaper rash?
See your pediatrician if: the rash has open sores, pus, or bleeding; spreads beyond the diaper area; is accompanied by fever; doesn't improve after 2-3 days of home treatment; or if you suspect a yeast infection.
