When to call the pediatrician
Sometimes a diaper rash needs medical attention. Talk with your pediatrician if:
- The rash does not look like it’s going away or gets worse 2 to 3 days after treatment. (See “What can I do if my baby gets diaper rash?”)
- The rash includes blisters or pus- lled sores.
- Your baby is taking an antibiotic and has a bright red rash with red spots at its edges. This might be a yeast infection.
- Your baby has a fever along with a rash.
- The rash is very painful. Your baby might have a skin condition called cellulitis.
