Diaper rash is a common problem for most babies, but there are some steps you can take to avoid it. Changing diapers frequently will help, as well as rinsing their bottom with warm water whenever diaper changes are made. It can be very helpful to expose your baby’s bottom to the fresh air with no diaper so that it has adequate time to dry. If a rash does appear, use a moisturizer or ointment regularly so that skin doesn’t become irritated or raw.
