Can Drinking Too Much Milk Causes a Toddlers Stool to Be White?

“Drinking too much milk causes a toddler’s stool to be white,” Are you curious to know the details of this? Then this article is for you.

Drinking excessive milk can cause your baby’s digestive system to be clogged and upset, resulting in white stool.

It also includes when you need to be worried and some other ways in which the poop of your baby might look during the first two years of his life.

We all think that “poop is poop,” but when we talk about a baby’s poop, it’s different as there is a whole spectrum of different textures and colors.

If the color of your baby’s poop is brown, green, or yellow, it’s normal, but again it depends on your baby’s current health status and diet.

Drinking Too Much Milk Causes A Toddler’s Stool To Be White, But Is It Harmless For Your Baby?

White stool in toddlers can indicate liver disease caused by excessive milk.

Sometimes, white stool in toddlers is just undigested bits of milk fat, indicating that the child has consumed too much dairy.

After taking milk, your toddler might poop. Rarely do babies and toddlers pass out white poop.

If the fat in the breast milk and your baby’s formula feed is not digested properly, it appears as white curds in your baby’s poop.

Most toddler formulas present in the market are based on milk. They are usually given to children about nine months to 3 years old.

Toddler formula differs from infant formula because it has greater sugar, fat, and sodium.

Another reason for the toddler’s white stool is a medical condition like liver. It can be the result of bile accumulation in the liver of your baby that can cause damage to the liver cells, leading to liver failure.

If this is the case, then it needs urgent medical care.

But then again, white stool because of drinking too much milk is not serious in all cases. It can be just because of some harmless reasons and a milk-only diet.

Undigested Milk Fat

Undigested milk fat could be a reason for white curds in your baby’s stool.

After drinking milk, if the fat in the milk does not completely break down in the baby’s stomach, it may appear like cottage cheese in the baby’s stool.

This problem mostly occurs in breastfeeding babies because of the higher fat content in breast milk.

The milk fat content in the formula feed is less, but they can still face this issue of undigested milk fat.

If your baby is drinking breast milk and otherwise does not have white poop and signs of illness and uneasiness, then the reason behind this is maybe the indigested milk fat.

Undigested Food:

If your baby is eating solid food, then the stool’s white chunks may be undigested food particles.

Your baby may be in the learning process of eating, he does not know how to chew the food properly, and his stomach has to bear all the new types of food that are also trying to tolerate.

Therefore, some food is pushed through the digestive tract before being fully digested.

Allergy to Milk Protein:

In children, the allergy to milk protein is very common as a food allergy. It is because of an allergic reaction to milk.

The body’s immune system considers the milk protein a hazard; therefore, it reacts by causing different symptoms ranging from mild to severe.

And in a result of this, your baby can also have tummy troubles and unusual color of poop.

Lactose Intolerance

Lactose intolerance is another reason for having white stool after drinking milk. In this case, the baby could not completely digest the lactose in the milk.

This is due to the less production of the enzyme in the baby’s small intestine required for the breakdown of lactose in the milk.

This leads to the inability of the digestive system to properly digest the milk-based products, which in turn results in stomach cramps and particularly stooling right after consuming milk products.


Bacterial, viral, and parasitic infections can also cause a change in the texture and color of the toddler’s poop.

However, the infection-based change in the appearance of poop is not very common.

Another way of knowing whether or not your toddler’s white stool is because of an infection is the following symptom:

  • Irritability
  • Runny nose
  • Cough
  • Fever (Over 100.4°F)

If the texture and color of your baby’s poop are changed suddenly, and the other symptoms are also present, then it’s time to call your pediatrician.

The remnants of the milk your baby consumes can lead to white stool, but it is important to note that it may also cause diarrhea.

All Milk Diet

Bowel disturbance can also be caused by a diet that includes only milk.

When a child drinks too much milk that exceeds his requirements and does not eat anything else that can provide essential nutrients, this can also lead to an unusual stool color.

Therefore, you must also introduce other foods into your child’s diet.

Antacids are used mostly for treating heartburn and sometimes for indigestion (because of the presence of too many acids).

However, using antacids has the side effect of causing toddlers’ stools to be white. So, if your baby takes antacids daily, check the side effects caused by that particular antacid.

What to Do If Drinking Too Much Milk Causes a Toddler’s Stool to Be White?

Reduce the daily intake of your toddler.

If you see an unusual color in your baby’s stool, it is important to reduce the daily amount of milk and replace it with other types of food.

Try to fulfill your baby’s needs with different kinds of food instead of filling his tummy with milk.

Give Formula Milk A Try From A New Brand.

If you feel that your baby has any problem with the digestive system after using any specific formula brand, try a different one because your baby may be reacting to that brand.

It will also ensure whether the formula milk brand was the real issue.

If the reaction was because of the milk-based formula brand, you could use non-milk-based formula milk or the formula specifically for babies with allergies.

Visit a Pediatrician

After changing the brand of your baby’s formula, if your baby continues to have a white stool, visit a pediatrician and conduct a test to identify the real cause of the problem.

Sometimes, a liver problem can cause your baby to have a white stool. However, this case is very rare.

Visiting a pediatrician is crucial for detecting the real cause and preventing a serious problem.

Final Words- Drinking too much milk causes a toddlers stool to be white

Mostly the white poop of toddlers is because of the undigested milk fat. It is more common for breastfeeding babies but can occur in formula-feeding babies too.

White poop because of undigested milk fat is not a serious issue; you don’t need to do anything different.

While white stool in toddlers may be concerning, it can be a positive indicator that your child is not eating enough, prompting you to adjust their diet accordingly.
