Diaper Rash - A Baby's Bottom Story


Diaper rash is common in babies and toddlers and is generally caused by the constant wetting and drying of delicate skin and exposure to irritants. No matter how clean and dry you keep your baby's bottom, they will likely develop a diaper rash at some point.

Some of the irritants that can cause diaper rash are:

  • urine
  • stools
  • bacteria from urine and stools
  • detergents
  • fragrances
  • plastics from disposable diapers
  • pre-moistened baby wipes
  • soaps.

Here are some of the more common types of diaper rashes:

  • Diaper chafing or chafing dermatitis
    • most common form
    • caused by the baby's bottom being wet too much or irritation from the diaper itself
    • the genital area and folds of the thighs and buttocks appear red and puffy
    • can be treated with a mild ointment.
  • Eczema or atopic dermatitis
    • may be caused by allergens, irritants, environmental factors, and/ or hereditary factors
    • usually affects babies 6-12 months of age
    • may develop on other parts of the body first and then spread to the diaper area
    • shows up as red, scaly patches on the legs and groin area

    • is aggravated by moisture and heat
    • can be treated with a medicated powder or an over-the-counter ointment.
  • Skin rubbing on skin (Intertrigo)
    • occurs when skin folds rub against each other and the resulting friction can cause a rash on baby's sensitive skin

    • is usually seen in the folds between the thighs and abdomen and sometimes in the armpits
    • can generally be treated by an over-the-counter ointment or powder.

Here are more some preventive measures you can use, but even with all the prevention in the world, your baby may still get a diaper rash:

  • Change your baby's diaper often, washing the skin with a wash cloth or cotton balls dipped in warm water.
  • Use an ointment such as DesitinŽ, A&DŽ, EucerinŽ, zinc oxide or NiveaŽ on your baby's bottom to form a protective barrier.
  • Give your baby's bottom more time in the open air without diapers on.
  • If your baby is having a recurring problem with diaper rash, try switching the type of diapers you are using.
  • Limit exposure to irritants such as soap. Washing your baby's bottom with soap 2-3 times per week is enough.

If the diaper rash doesn't improve in a day or two, take your baby to see your doctor.
