The diaper area represents a large moist and humid, occluded environment which is more prone to maceration and attack by microorganism. The skin is also in contact with strong alkalinizing agents e.g. urine and feces and the high pH damages the skin integrity and causes irritant diaper dermatitis. The mother should be advised to frequently change napkins, whether they are home laundered or of the superabsorbant variety. The skin should be dried and aired between napkin changes. If frequent changes are not feasible, mineral oil can be used on buttocks to form a physiologic barrier. Warm water and soft cotton wool can be used to wipe napkin area. The bottoms should be wiped from front to back. For feces that sticks, an emulsion like baby lotion can reduce the surface tension and clean the debris. If a napkin rash occurs, petrolatum jelly or zinc oxide containing pastes can be used.
