Infant hiccups after breastfeeding is an extremely common phenomenon, mostly physiological phenomenon, but if the baby appears frequent or persistent hiccups, then alert disease factors, such as neonatal intracranial hemorrhage, meningitis, etc., need to consult the doctor in time for investigation. 1. Physiological phenomenon: Infant hiccups may be caused by the baby eating more milk, stimulating the diaphragm, or it may be caused by the baby failing to contain most of the areola during breastfeeding, or the baby’s poor connection and mixing with air, which is a normal phenomenon. Hiccups can be minimized by adjusting the feeding method and patting the baby’s back after feeding. 2. Neonatal intracranial hemorrhage: Intracranial hemorrhage may occur due to the baby’s own abnormal coagulation function, abnormal development of intracranial arteries and veins, and birth injury during delivery. The child may have irritability, persistent hiccups, convulsions, vomiting and other manifestations. 3. Meningitis: infants with frequent hiccups, accompanied by vomiting, headache, impaired consciousness and other signs of increased intracranial pressure, should be alert to the occurrence of meningitis, usually due to bacterial infections invading the meninges of the newborn, but also accompanied by fever, refusal of breastfeeding, low response and other manifestations. If hiccups occur too frequently or persistently in infants, parents should pay attention to them and take their babies to the pediatrician in a timely manner to improve the relevant examinations and detect the presence of the disease.
