What is the reason for the baby having loose stools after switching from formula to breast milk?

Patient's question:

No

Doctor's answer:

Hello, the current situation is that when intestinal function is poor, you want to switch back to breast milk, but switching abruptly is not the right way. Now, with another episode of diarrhea, please completely switch back to the diarrhea formula. Wait until the stool is normal for two or three days, then use a gradual weaning method to complete the transition. It should take at least a week, gradually increasing the amount of breast milk each day.
