How can I get rid of baby hiccups?

You can't. 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.
