Do antibiotics for a 3-month-old baby destroy the intestinal flora?

Antibiotics can sometimes disrupt the balance of "good bacteria" in the intestines, leading to issues such as diarrhea or other infections. However, if a doctor has prescribed the antibiotic for your child, they likely believe that the benefits of the medication outweigh the potential risks of side effects. To provide a more accurate answer regarding the consequences, it would be important to know the specific antibiotic being taken and the medical reason for its prescription.
