8 Causes and Treatment of Vomiting after Breastfeeding of Infants

Some parents think it is normal for babies to vomit after breast-feeding, but at least you need to know the reason and treatment.

Vomiting of infants after breast-feeding usually lasts for several hours. Intermittent vomiting will occur within these hours. Generally, no special treatment is required.

However, sometimes babies vomit with crying, resulting in a large amount of breast milk being spit out.

Breast milk is an important food for the first six months of a baby’s life, and you may worry about malnutrition.

What causes vomiting after breast-feeding, and how should you handle it?

It may not be unusual for babies to vomit, but you need to understand the cause and treatment.

Causes of vomiting of infants after drinking breast milk

One of the reasons why babies vomit after drinking breast milk is gastrointestinal discomfort.

This situation may be caused by a variety of reasons, such as intestinal dysplasia of premature infants, and the most common reason is the food and drink that mothers eat while breastfeeding.

The following are the foods and drinks that some mothers eat, as well as the diseases that cause vomiting after breastfeeding:

1: spicy food

Spicy food is the cause of heartburn and stomach acid rise.

If you eat spicy food and breast-feed, this may lead to gastrointestinal discomfort of the baby, which may also lead to vomiting of the baby after breast-feeding.

Adding spicy seasonings such as chili or pepper to food will stimulate intestinal tract and gastric mucosa, causing stomach discomfort.

As the baby’s food depends on breast feeding, spicy food eaten by the mother may have adverse effects on the sensitive stomach in development.

2: Caffeine

Caffeine intake leads to looser adductor muscles in the lower esophagus, which may lead to increased gastric acid and nausea.

If you drink caffeinated beverages before breast feeding, this may cause caffeine to enter the baby’s body through breast milk and cause reactions.

A small amount of caffeine may have little effect on your baby, but if your baby vomits or has other adverse reactions, please stop consuming caffeine drinks.

3: Non-natural fruit juice

Bottled fruit juice available on the market should be avoided by breastfeeding mothers, because it contains a lot of preservatives and additional sugar and artificial sweeteners.

Bottled fruit juice is not easily digestible by a sensitive baby’s stomach, which leads to gastroesophageal reflux.

4: Cabbage

Too much eating of raw cabbage or cabbage has been shown to cause gastric acid in adults, because the nature of this vegetable can irritate the digestive system.

Infants who are fed exclusively by mothers who consume cabbage, may experience heartburn and vomiting.

5: Broccoli

There is no doubt that eating this vegetable will cause vomiting in infants.

Though Broccoli is a very good food for health, but adults or nursing mothers consume green vegetables this can cause feelings of bloating.

If you find your baby vomiting after breast feeding, please check if you eat broccoli.

6: Infection

The vomiting of infants after drinking breast milk may be due to infection.

Newborns’ immune system is still developing, so they are vulnerable to infection.

Whenever a baby is infected, his immune system may not be able to stop all invaders like adults.

Almost all children will come into contact with gastroenteritis (infection caused by virus and bacteria) before the age of five, so the incidence rate of infants will also increase.

If you have gastroenteritis, your baby may have diarrhea and vomiting.

If the age is less than 6 months, the mother can take her to see a doctor, or drink a lot of milk at home to fully treat to avoid dehydration.

If the baby is short of drinking water or has a fever, see a doctor immediately.

7: Milk protein allergy

If a baby is allergic to drinking milk, it is likely that his immune system is sensitive to proteins in dairy products.

If the mother drinks milk or eats milk-based foods such as cheese and yogurt, breast milk also contains a small amount of protein, which may cause vomiting of the baby.

Compared with infants who drink breast milk, infants who drink formula milk are more likely to be allergic to protein in milk.

If the baby is allergic to protein, he may vomit after drinking milk.

If the baby is allergic to the protein in milk, the baby will probably have the following experiences:

  • Diarrhea
  • Constipation
  • Eczema

8: Pyloric stenosis

The cause of vomiting after a baby drinks a glass of milk may be pyloric stenosis, which is a rare condition and can cause vomiting of the baby.

This is because the muscle control valve from the stomach to the intestinal tract has thickened, which means that breast milk will not enter the intestinal tract through the valve at the bottom of the stomach.

On the contrary, milk will stay in the stomach or the baby will spit it out.

When the baby is about 6 weeks old, pyloric stenosis may begin to appear.

At first, after breast feeding, the baby will begin to vomit, slowly the situation will get worse, and the baby will vomit more times.

The vomited milk is likely to thicken and turn yellow.

Boys are more likely than girls to develop pyloric stenosis, which can be treated by minor surgery.

If you find that your baby has been vomiting and it is difficult to improve through diet, go to a doctor for treatment immediately to ensure that the child maintains sufficient water and food.


How to overcome infant vomiting after drinking breast milk?

Usually, babies vomit much after drinking breast milk should not be feared, because it will improve soon. However, if our mothers are worried, here’s what our mothers can do to help restore it:

1: The baby takes in enough water

When vomiting, babies lose body fluids.

Therefore, it is very important to replenish the lost water so that the baby will not dehydrate.

In addition to regular breastfeeding or formula milk, mothers can also give their babies several oral rehydration solutions within one hour.

Consult a pharmacist before trying. Remember, don’t give your baby fruit juice or soda.

2: Maintain regular eating

If the baby does not vomit for 12 to 24 hours, he can start eating ordinary food.

But the best thing is to nurse the baby.

However, if your baby is eating solid food, you can start with foods that are easy to digest, such as cereal or yogurt.

3: Help the baby rest

Sleep can also help calm your baby.

When sleeping, the food in the stomach will empty into the intestinal tract, thus eliminating vomiting.

Under normal circumstances, do not give the baby medicine, unless it is the doctor’s advice.


The above are suggestions and measures for vomiting after breast feeding. Please pay attention to your baby’s condition. If necessary, medical measures are necessary.

If you find that your baby can’t stop vomiting, please consult a doctor immediately instead of trying to find your own way.
