Diaper contents left in contact with an infant’s skin for an extended time can cause physical irritation or infection due to the urine changing the skin pH level, allowing bacteria and fungi to grow. Also, the newer tightly sealed diapers stop air circulation
Allergies may also cause rashes to form. These reactions may be to detergents, dyes in diapers, or cleaning wipes. Occasionally changes in foods may cause changes in the consistency of diaper contents.
To prevent rash, keep the infant’s skin dry and clean and change diapers often. Creams with zinc oxide or petroleum may be used. Rashes should clear up in two to three days.
Consult a healthcare provider if rash does not go away, if sores appear, or if child is feverish.
