Most of the hiccups after breastfeeding are caused by air entering the stomach because the baby was fed too quickly or the mother’s breastfeeding posture was incorrect. The digestive tract of infants is not yet well developed, the stomach is horizontal, and the pancreatic sphincter is relatively loose, so when parents feed too fast or too fast, the head is slightly lowered, or the baby’s lips do not completely wrap the areola or the pacifier, etc., it is easy to cause the air to enter the stomach with the swallowing action, and if parents do not burp in time after breastfeeding, the above symptoms will easily occur. This is a normal physiological reaction, and parents can help their infants to improve the symptoms through timely back patting and venting. Babies burping after feeding may also have other causes, such as pneumonia, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
