So, What Are the Foods That Cause Diaper Rash in Toddlers?

Changes in bowel movements like loose stools for babies are caused by progression to solid foods, which can be the primary cause of diaper rash.

We need to be aware that certain foods like fruits, juices, and other acidic foods in the baby’s diet can be the common cause of diaper rash that gets worse.

Read below to find out about the possible foods that irritate your children’s digestive system and cause severe diaper rash!



Because they are highly acidic foods, tomatoes can worsen the diaper rash on your baby’s bottom.

The best thing you can do for now is to AVOID any tomato-based foods like…

  • Tomato soup
  • Tomato-based sauces like ketchup
  • Spaghetti sauce
  • Or anything else with a base that’s made with tomatoes

The acidic content of tomato-based products may irritate the diaper rashes, making your baby’s diaper rash more exaggerated and uncomfortable for your little one, so please keep this in mind!



Ahh, yes. Strawberries!

We all know that everyone loves these sweet little treats, but like the tomato, this fruit is also HIGHLY ACIDIC and can irritate the skin of your baby.

Letting your baby consume the fruit or even products made of strawberries can make the diaper rashes more painful!

Citrus Fruits


Your children may be obsessed with citrus fruits, too!

I mean, most children LOVE a nice and cold bottle of lime juice and slices of oranges.

Of course, we all know that citrus fruits like oranges, limes, and lemons are ACIDIC, as well!

It’s best to be cautious and stay off the oranges. These sweet little fruits are your baby’s favorites that can cause diaper rash.

Pineapple Fruit


Your children may LOVE eating pineapples because Spongebob lives in one!

All jokes aside, their sweetness and juicy taste will have them craving for more.

However, you need to be aware that this delicious fruit is also EXTREMELY ACIDIC, resulting in a diaper rash.

Alternatively, you can also introduce new foods for babies to enjoy, like papaya and mango! These are definitely delicious fruits that aren’t acidic.

Trust us, your babies will enjoy them, and you can bid the diaper rash away!



Don’t be surprised if your baby starts asking for carrots like their favorite cartoon rabbit!

But before letting your little one indulge in this sweet orange treat, you might want to confirm if they may have a food allergy to carrots!

You can see common diaper rash symptoms to check for allergies on specific foods on their sensitive, inflamed skin like

  • Eczema
  • Hives
  • Facial swelling on the face or inside the mouth

Other diaper rash symptoms might include frequent wheezing, fainting, or indigestion.

Being mindful of these can help prevent diaper rash on your baby’s precious skin!

Milk and Formula

Baby formula is good for your baby’s growth, of course! It contains the essential nutrients that the baby needs to blossom into the best child they can be.

As parents, we want that for our children, without a doubt!

But of course, we need to be more aware of the possible discomfort that your child has with a milk-based formula, ESPECIALLY if your child has a milk allergy.

If your little one has a milk allergy, this can cause severe diarrhea, and diaper rash will be the effect!

When you frequently do a diaper change and notice the effect of diarrhea in your baby’s diaper, it means their digestive system isn’t taking it well.

DIARRHEA could be caused by the baby’s system having a hard time processing the proteins found in milk and is a common cause for them to develop diaper rash.

But Don’t Worry! You Can Always Get Milk Alternatives for Your Little Ones!

A wonderful substitute and solution to your child’s food sensitivities are to try SOY MILK, ALMOND MILK, or GOAT’S MILK FORMULAS!

We HIGHLY recommend these for your baby!

These are HEALTHY ALTERNATIVES for your little one to stop the diaper rash!

If you notice that the diaper rash situation stopped as you switched to alternatives, then you and your baby are all set!

What Causes Diaper Rash?

Babies are bound to try an assortment of other foods as they grow older (e.g., whole grain cereal and maple syrup for babies), which can confuse you as to what kind of food causes diaper rash to your baby’s skin.

This is often related to wet diapers that irritate your children’s skin, which can be a HUGE PAIN!

Diaper rash can alarm us as parents and is an incredibly uncomfortable experience for your baby.

You should always look for the following signs that are an effect of diaper rash on your babies:

  • Red and irritated skin along the diaper region of your children
  • Your baby shows constant signs of discomfort or pain, especially during a diaper change when you touch the affected diaper area.

How Can Diaper Rash Be Treated?

Being more aware of the roots of the problem or the kind of food that can cause a diaper rash for your babies is the first step to TREAT diaper rash.

  • Try to identify the foods that cause diaper rash by introducing newer foods to them ONE-BY-ONE!
  • Double-check if the baby food or formula is expired. This could be a reason why your baby’s tummy is acting up!
  • Remove wet diapers IMMEDIATELY, as the moisture inside can cause diaper rash.
  • Avoid using baby wipes. Some chemicals might react strongly to your baby’s sensitive skin.
  • NO spicy or hot foods!
  • You can try starchy foods like pasta that are easily digested to ward off diarrhea.
  • Also, try to consider ointment, diaper cream, or barrier cream that has ZINC OXIDE to ease the diaper rash!

  • Getting worse despite the home treatment
