Is it normal for a fetus to frequently hiccup in the womb?

It is normal for a fetus to hiccup in the womb. Inside the uterus, the fetus needs to swallow amniotic fluid to promote lung development and gastrointestinal tract maturation. During this process, if the diaphragm is stimulated, it can trigger hiccups. Fetal hiccups help exercise lung development and enhance gastrointestinal responsiveness. Typically, fetal hiccups do not last very long. If the pregnant woman experiences any discomfort during this time, she should seek medical attention immediately.
