When should I call the doctor about diaper rash?

Sometimes a diaper rash needs medical attention. Talk with your baby’s doctor if:

• The rash does not look like it's going away or gets worse two to three days after starting treatment
• The rash includes blisters or pus-filled sores
• Your baby is taking an antibiotic and has a bright red rash with red spots at its edges
• Your baby has a fever along with a rash
• The rash is very painful
• You suspect a yeast infection
