How long does a baby change from one brand of formula to another?

Patient's question:

No

Doctor's answer:

Generally speaking, if a baby is suitable for a brand, don't change it randomly. Babies are still young, and their stomachs can't adapt easily. If a baby gets used to a certain taste, don't change it either. Otherwise, the baby might refuse to eat, which would be counterproductive. Nestlé's NAN Gold Shield contains probiotics and DNA.
