Doctor's answer:

I'm glad to help you clarify this. Hiccups are caused by recurrent severe contractions of the diaphragm muscle. In children, frequent hiccups are due to the underdeveloped growth of the vegetative nervous system that adjusts the diaphragm. When a child is slightly startled, such as inhaling cold air while drinking milk too quickly, the diaphragm suddenly contracts, striking the diaphragm and causing hiccups.
During hiccups, coughing occurs because the diaphragm muscle is struck, which doesn't require excessive concern. These situations can be relieved as long as the diaper-changing method is correct.
The above is my suggestion for the question "Why does my baby occasionally cough and feel nauseous?" I hope it helps you. Wishing you good health!
