What to do for a 3-month-old infant with diarrhea

When a 3-month-old infant develops diarrhea, parents should first observe the baby's symptoms, such as whether the frequency of bowel movements has significantly increased (usually more than three times per day), whether the stool has become loose or watery, and whether there are accompanying symptoms such as vomiting or abdominal pain. The following measures can then be taken: 1. Adjust the diet: If the baby has already started complementary feeding, it is recommended to temporarily stop and return to exclusive breastfeeding. Mothers who are breastfeeding should pay attention to their own diet, avoiding overly greasy, raw, or cold foods. 2. Replenish fluids: Diarrhea can easily lead to dehydration, so parents should ensure the baby receives adequate fluid intake; oral rehydration salts may be used when necessary. 3. Avoid misuse of antibiotics: Unless the cause is known, avoid using antibiotics in infants to prevent disruption of the intestinal environment. If the diarrhea symptoms persist or worsen, prompt medical attention is necessary so that the doctor can provide targeted treatment based on the underlying cause.
