Diaper rash is usually managed and treated at home without a doctor’s supervision. There are cases, however, when it’s best to call a pediatrician.
The American Academy of Family Physicians offers these warning signs that diaper rash should be evaluated by a doctor:
The rash breaks out when the baby is 6 weeks or younger.
The rash has small ulcers or pimples.
The rash is accompanied by fever, nodules or large bumps.
The infant doesn’t look well or has lost weight.
The rash spreads beyond the diaper area, including to the scalp, face or arms.
The rash doesn’t improve with treatment after a week.
