Will a child have diarrhea after drinking some first-stage formula and then switching to second-stage formula?

Patient's question:

No

Doctor's answer:

Hello, when a child has been drinking a certain brand of formula, switching to the same brand's second-stage formula generally does not cause diarrhea. Of course, some children may have a weak spleen and stomach, and may also experience such symptoms. Therefore, when switching formula, you can mix it with the old formula for a few days for the child.
