Little babies are especially prone to spitting up, which is very common and happens to most infants. What’s wrong with babies who burp after drinking milk and still spit up? Spitting up is related to these causes Spitting up is most commonly seen in infants 1-2 months after birth. The causes of spitting up are related to the anatomical and physiological characteristics of the infant’s digestive tract. The infant’s stomach is horizontal, the sphincter at the entrance of the stomach (cardia) is more relaxed, while the exit (pylorus) is relatively more tense, which makes it easy for milk to flow back into the esophagus and be spit out through the mouth. In addition, at this time the baby’s neuromodulation function is not perfect, if the feeding method is not appropriate, such as inhaling too much air when eating milk, sucking the nipple, etc., will aggravate the milk spit up. How to prevent spitting up? Spitting up is not a big concern as long as it does not occur frequently. If spitting up occurs frequently and the baby is not properly cared for, it can lead to serious consequences – choking. This occurs when a large amount of spit-up is sucked into the windpipe and becomes blocked. On the other hand, spit-up can flow into the Eustachian tube, causing a secondary bacterial infection and otitis media. In order to avoid spitting up, should pay attention to the following aspects of the problem: 1, the baby is hungry without timely feeding, the baby will cry hard, in the process of crying sucked a lot of air, easy to vomit after eating milk. Therefore, newborns should be fed on demand, and for babies after 1 month, about every 3-4 hours. 2, change the diaper before feeding, and move the baby as little as possible after feeding. 3, after feeding the baby upright, gently pat his back, and then put the baby flat after hiccups. 4, the baby has just eaten do not shake around, this is easy to cause the baby to vomit. 4, the baby lying down to sleep, the upper body should be slightly elevated, so that the milk easily through the stomach into the duodenum. Under normal circumstances, because of eating too much, even after eating milk burping, immediately lying down, milk is also easy to open the cardia, through the esophagus back to the mouth, resulting in spitting. If your child spits up once in a while and is in good spirits, there is no need to worry.
