What causes babies to hiccup?

Baby hiccups may be caused by various factors. First, since an infant's intestines are not fully developed, the digestive system often does not function properly, leading to indigestion and ultimately causing hiccups. Second, if the baby's gastrointestinal function is immature and the digestive system cannot operate normally, this can also result in hiccups. Additionally, poor eating habits may trigger this condition. If the baby consumes excessive spicy or greasy foods, the stomach may become irritated and cause hiccups. If this condition persists, it is advisable to seek medical attention promptly and follow the doctor's instructions for treatment.
