Diaper rash typically appears on the skin of infants and younger children under their diaper. It may happen to almost every baby at least for once during the first 3 years of life, and it is more likely to happen to the 9-12 months old babies. This is the time when the baby is still sitting most of the time and is also eating solid foods, which may change the acidity of the bowel movements.

Negligence in hygiene of baby results in diaper rashes. It is necessary to take some extra care on terms of hygiene of infants. The main causes of diaper rashes are not just limited to the baby's hygiene, but there are several factors which causes diaper rashes:

• Friction: One of the main cause of diaper rash is when the sensitive baby skin is rubbed by wet diapers resulting in a red, shiny rash on exposed areas.
• Irritation: The diaper or the acid in urine and bowel movements can cause irritation.
• Fungal or yeast infection: Such infection is very common after the use of antibiotics. It usually has a bright, beefy red appearance.
• Allergic reaction: Diaper wipes, diapers, laundry detergent, soap, lotion may cause a reaction that results in rashes on the skin.
• Seborrhea: This may appear on the other parts of the body like face, head and neck of the baby in appearance of an oily, yellow-colored rash.
• Bacteria: These causes are less common but bacteria like staph can cause rashes to the baby's skin.

It is fairly easy to identify a diaper rash. More usually the rashes appear on the skin underneath the diaper area. Diaper rashes make skin red and irritated. It may appear all over your baby's bottom or genital area, or only in certain places.The affected skin may also be warm to the touch.

There are usually four types of diaper rashes:

1. Irritants: This is the most common type of the diaper rash caused by diaper itself and wet skin being in contact with the diaper
2. Candida: Candida is a kind of infection caused by fungal and yeast overgrowth. Diapers are the perfect place for yeast or fungal to thrive as it grows rapidly in a warm, moist environment.
3. Allergic: Such diaper rashes occurs due to an allergic response caused by contact with chemicals and materials in the diaper, wipes, diaper cream, lotion, soaps, shampoos, or laundry detergents.
4. Bacterial: The most common reason of bacterial dermatitis to happen is Staph. Bacterial rashes often occur when the baby skin is already irritated or has small cuts and abrasions usually from vigorous wiping or other reasons.
