If you see any of these symptoms in your baby’s diaper area, then call the pediatrician:

• 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 also 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
