When the baby vomits milk, the substance expelled resembles water with milk curds mixed in and has a slight acidic taste, which is usually a small signal from the digestive system. Since the baby’s digestive system is still developing and may not be fully mature, indigestion is a common cause. During feeding, avoid overfeeding the baby, as both overfeeding and indigestion can exacerbate the vomiting phenomenon. The sour taste in the vomit is mainly due to the milk undergoing fermentation in the baby’s stomach for a period of time. To help alleviate this situation, gently pat the baby’s back after feeding to promote gas expulsion, which may improve the situation.
Observing the baby vomiting with milk curds and acidic taste likely indicates that the digestion process is not ideal. In terms of strategy, you can try implementing a plan of small, frequent meals for the baby, especially for formula-fed babies, you can slightly dilute the formula to reduce the burden on their digestive system.
Many parents find that their babies’ vomit often has a yogurt-like sour taste, which is the result of the milk naturally fermenting briefly in the mouth and stomach. When faced with this situation, you can rinse the baby’s mouth with a small amount of clean water after vomiting, which helps clean the mouth and maintain a good oral environment. It is important to note that if the baby vomits frequently and in large amounts, accompanied by weight loss or other abnormal symptoms, you should consult a professional doctor promptly to rule out possible pathological factors, such as pyloric stenosis, a rare condition. Minor vomiting or “spitting up” under normal circumstances, as long as the baby is overall healthy, usually does not require excessive worry.
