I'm 9 months pregnant. I feel my unborn baby has way too many hiccups.?

Very common. Babies have hiccups a lot in utero, and then can have a lot after! i would not be worried.
Get used to it. Hiccups are thought to be triggered by an electronic event passing through the babies breathing muscle triggered by rubbing the nearby stomash.This is common in some infants.Those that do in the womb usually continue during the first weeks/months after birth.It generally stops when the baby grows longer, separating the stomach from the breathing muscle.Frustrating but harmless.
Let's ask Peds/ENT. I am going to share this with the doctors who know babies about the size of yours --pediatric ENT and general ENT and peds.
