Parents can feed their babies on demand or on time and control the speed of milk flow, as well as burp after feeding, as follows: 1. The baby should not be overly hungry, so as not to eat too fast or too quickly in the process of breastfeeding and swallow some air in the stomach with the swallowing action. 2. Control the speed of milk outflow: Parents should control the speed of milk outflow, and when the milk flows out too fast, use the index and middle fingers to hold the areola part. If you have a baby with a milk powder, you should choose the right pacifier, and the pacifier hole should not be too big to prevent the milk from flowing out too fast and the baby from swallowing too fast and swallowing the air in the stomach. 3. burp: after feeding the baby, parents should hold the baby vertically, with the head lying on the parents’ shoulder, and parents should hold the baby’s buttocks and back with one hand and pat the baby’s back with the other hand to help the baby expel the air in the stomach, which can reduce the occurrence of vomiting. This can reduce the occurrence of vomiting.
