Generally babies before three months of age are most likely to spit up, especially in the second to third month when spitting up is more serious.
Most babies spit up related to their own physiological characteristics, mostly seen in babies before three months. During this time period, as babies are relatively young, their stomachs are horizontal and the cardia sphincter is relatively loose, so if they are not fed properly, for example, if they are fed too much milk, they will be prone to spitting up.
The phenomenon of spitting up will gradually decrease after three months, and after six months, when complementary foods have been gradually added and gastrointestinal development has been perfected, babies seldom spit up again. If it is only physiological, parents do not need to worry too much.
If your baby spits up a lot, you can try to change the way you feed him or her, following the principle of small amounts and many times. After each drink, you can put it on your shoulder and gently burp it to minimize spitting up.
In addition, if you continue to spit up a lot of milk and accompanied by fever, poor mental state and other symptoms, you need to be admitted to the hospital in time to identify the cause of the disease, so as not to miss the opportunity.
