Identifying Diaper Rash

What does it look like?

Diaper rash usually shows up as a patch of pinkness or redness, and scaling skin where the diaper meets baby's bottom.

A baby with diaper rash may also cry or fuss when being changed or washed.

A bad case of diaper rash usually causes pimples, blisters and other sores on your baby's buttocks, thighs or genital area. If the rash gets infected, it may be swollen and turn bright red.

Slight diaper rash Slight
Mild diaper rash Mild
Moderate diaper rash Moderate
Severe diaper rash Severe

Call your baby's doctor if:

  • The rash gets worse or does not go away in 2-3 days
  • The rash spreads to the abdomen, back, arms, or face
  • You notice pimples, blisters, ulcers, large bumps, or pus-filled sores
  • Your baby has a fever along with the rash
  • Your baby is taking an antibiotic and develops a bright red rash with spots at its edges. This might be a yeast infection.
