Vomiting is considered a normal phenomenon because the child is still small and the stomach is horizontal, which can easily cause the child to vomit, so holding the child up after each feeding and patting the child’s diaphragm can prevent the child from vomiting. However, if the child vomits severely, it may be due to a stomach disorder or a deficiency of the spleen and stomach. It is best to take your child to the hospital for a checkup and take reasonable medication under the guidance of a doctor to regulate the situation. If the child’s spleen and stomach is weak, it is best to take spleen pellets under the guidance of a doctor, give the child regular medical checkups to see how the baby is developing, and if the child is breastfeeding, the mother’s diet should be light.
