What is diaper rash?
Diaper rash may occur when a baby’s bottom is wet or exposed to soiled diaper contents for a bit too long, and then encounters friction from the diaper rubbing against the skin, causing a rash.
Diaper rash symptoms in the diaper area (genitals, buttocks, thighs) include:
- Slightly reddened skin
- The area may be warm to the touch
- There may be a few isolated diaper rash spots, or the rash may cover the whole area
- Your baby may also seem fussy or irritable, especially during diaper changes
Can certain foods contribute to diaper rash?
Other common causes of diaper rash
In addition to certain foods, other factors that contribute to diaper rash include:
- Stool, urine, or illness: Your baby’s skin is very sensitive and can quickly become irritated by stool and urine. This can intensify when they are sick or have diarrhea2.
- Infection: this is the second most common cause of diaper rash, with a yeast infection being the most common3 Learn how to tell the difference between a diaper rash from skin irritation and a yeast infection.
- Friction: If your baby’s diaper or clothing is too tight, this can lead to chafing, rubbing, and irritation2.
- New products: Have you recently switched to a new brand of diapers, wipes, laundry detergent, or lotions? These can all potentially cause a reaction in baby’s sensitive skin2.
- Antibiotics: Unfortunately, antibiotics can impact the healthy balance of bacteria in your baby’s gut. This can lead to diarrhea which may trigger diaper rash2.
4 common foods that may contribute to diaper rash
While diaper rash may be caused by a number of different foods depending on your baby’s digestive system, there are some foods that more commonly contribute to diaper rash due to their acidity and tendency to cause loose stools:
- Citrus fruits. Most toddlers love fruit, but if they are prone to diaper rash, be cautious about acidic citrus fruits like orange, grapefruit, lemon, lime, or juices made from these fruits.
- Tomatoes are another common contributor to diaper rash due to their acidity. To help avoid acidic stools, avoid tomatoes and any foods containing tomatoes like spaghetti sauce and ketchup.
- Strawberries. Though not considered a citrus fruit, strawberries are acidic and, despite their sweetness, may cause digestive irritation leading to acidic stools, potentially causing diaper rash.
- Pineapple. Pineapple is another sweet yet acidic fruit. For other tropical fruit alternatives, consider banana, mango, or papaya.

If your baby is experiencing diaper rash, thankfully there are some steps you can take to help soothe their skin so it can heal:

How to help prevent diaper rash
Preventing diaper rash involves similar tips to soothing existing diaper rash. Here are some simple steps you can take to help prevent diaper rash:
- Change your baby’s diaper frequently to avoid prolonged contact with wetness and soiled diaper contents. When changing their diaper, be mindful of potentially irritating baby wipes or other products. If using wipes, opt for fragrance- and alcohol-free wipes designed for baby’s sensitive skin. Alternatively, you may wish to gently wipe with plain water or a mild baby-safe cleanser with a washcloth2.
- Expose your baby’s skin to the air as much as possible and let your baby go diaper-free when possible2
- Monitor your baby’s reactions to new foods, particularly those commonly associated with diaper rash, and adjust accordingly to help prevent loose stools.
