My 2week old baby almost always hiccups after every feed.is this normal?why do the hiccups occur?

hiccups: Hiccups occur when the phrenic nerve which innervates the diaphragm fires irregularly. This can be due to many reasons. In an infant i don't think it would be a reason for concern but please speak with your pediatrician.

common: This process usually starts before birth and will subside on its own as baby grows longer.Some speculate that the closeness of the baby stomach to the breatiing muscle ; frequent feeds set off the process. As baby enlongates, the stomach drops down ; quits rubbing the diaphram ; the process quits triggering. It bothers adults more than the baby, so let them be.
