What Should You Do If Your 3-Month-Old Baby Has Diarrhea?

Infantile diarrhea—also known as infantile digestive dysfunction—is an acute gastrointestinal functional disorder occurring during infancy and early childhood. Its incidence peaks during the summer and autumn months, with diarrhea and vomiting being the predominant symptoms. With appropriate treatment, infantile diarrhea typically resolves rapidly. However, if left untreated, severe cases may lead to life-threatening disturbances in water and electrolyte balance, endangering the infant’s life. So, what should be done when a three-month-old baby develops diarrhea? The following section addresses this question.

What to Do When a Three-Month-Old Baby Has Diarrhea

1. General Management

For infants under six months of age who are exclusively breastfed, breastfeeding should continue. For formula-fed infants, regular formula or dairy products previously consumed by the infant may be continued. In mild cases, milk intake may be slightly reduced. However, if diarrhea is severe, oral feeding should be withheld for 8–24 hours, and intravenous fluid replacement initiated.

2. Protecting Delicate Skin

Diapers must be changed frequently. The infant’s buttocks should be thoroughly cleansed with warm water after each bowel movement and gently patted dry.

3. Appropriate Dressing

Clothing for infants and young children should be adjusted according to ambient temperature—adding layers when it cools and removing them when it warms—to prevent overheating. Abdominal exposure during sleep, especially at night, should be avoided. In summer, ensure adequate hydration and avoid overfeeding or foods high in fat.

4. Monitoring Weather Changes

Adjust clothing promptly in response to temperature fluctuations and ensure adequate abdominal warmth. After each bowel movement, gently cleanse the perianal area with warm water, change diapers frequently, dispose of soiled diapers properly, and wash hands thoroughly with disinfectant to prevent reinfection. Additionally, encourage age-appropriate physical activity to strengthen immunity and help prevent common illnesses such as colds, pneumonia, and otitis media.

Additional Information: What Foods Are Beneficial for Babies with Diarrhea?

1. Boiled Apples

Thoroughly boiled apples possess astringent properties. Feeding one boiled apple daily may help alleviate infantile diarrhea. To prepare, steam apples or boil them with a small amount of rock sugar to enhance palatability.

2. Carrot Soup

Carrots are alkaline foods rich in pectin, which helps solidify stools and bind bacteria and toxins on the intestinal mucosa—making them an effective natural antidiarrheal food.

3. Charred Rice Porridge

First grind rice cereal or infant rice cakes into a fine powder, then toast until golden brown. Add an appropriate amount of water and sugar, and simmer until thickened into a smooth porridge. The charring process enhances the adsorptive and antidiarrheal properties of the rice starch.
