If a newborn baby needs to be fed after vomiting, it should be analyzed according to the situation. 1. If the vomiting is very mild, just a little bit, in good spirits, without other digestive tract abnormalities, because the child does not have enough milk to eat, the parents can continue to feed the child; 2. If the vomiting is particularly severe and occurs after eating a little, it is often caused by digestive tract abnormalities, such as pyloric obstruction or intestinal obstruction, or even encephalitis of central nervous system infection, etc. Parents should stop breastfeeding the child in time and find the specific cause for appropriate treatment.
