Switching infant formula may cause diarrhea in babies, which is mainly related to several factors. 1. If the new formula is unsuitable for the baby's current stage—for example, if it contains excessive protein and the baby has a protein allergy—it may trigger diarrhea. 2. Improper methods of switching formula can also lead to diarrhea. If the new formula is introduced directly without gradually mixing it with the previous one, the baby's digestive system may not adapt well, resulting in diarrhea. 3. If the formula is contaminated by pathogenic microorganisms, it may cause gastrointestinal infection and subsequently lead to diarrhea. If a baby develops diarrhea, prompt medical attention should be sought, and treatment should follow the doctor's recommendations.
