Question
Why isn’t the newborn gaining weight?
Answer
When a newborn’s weight does not increase and is accompanied by symptoms of lactose intolerance such as frequent diarrhea and nausea or vomiting caused by lactose intolerance, it may be due to a lack of lactase in the body, preventing the full digestion of lactose in breast milk or formula milk. According to the description, it is suggested that you can temporarily switch to lactose-free formula milk to feed the baby. Once the nausea and vomiting improve, you can gradually increase the frequency of breastfeeding and can try mixing breast milk with lactose-free formula milk while paying attention to keeping the baby’s abdomen warm.
