Patient's question:
Baby was born 34 days old, and I switched to formula feeding because of insufficient breast milk, then he started having diarrhea. The diarrhea was watery and green. I first gave him Mamiyai, and then switched to Similac. Is that okay?Doctor's answer:
Hello. A one-month-old baby should not be changed to a different formula frequently. At one month old, a baby's gastrointestinal system is not fully developed. Constantly changing formulas can lead to either diarrhea or constipation in the baby. If you want to switch to a different formula, you can try it after the baby is four months old. By then, the baby's stomach will have produced digestive enzymes that can adapt to the change in formula. However, even for a four-month-old baby, there should be a gradual transition process when switching formulas. For example, the new formula can initially make up one-fourth of the total formula, and if the baby shows no reaction after two days, the new formula can be increased to one-third of the total formula. After another two days with no issues, the new formula can be increased to half of the total formula. Finally, the new formula can completely replace the old one. This method of switching formulas ensures that the baby will not have any adverse reactions.
