Fetal hiccups are a normal phenomenon, the same as normal adult breathing. Because the fetus’ lungs are not fully developed, it has to swallow amniotic fluid constantly. Swallowing amniotic fluid exercises the lungs to breathe, so fetal hiccups are a way to exercise the breathing ability of the lungs. If the fetus hiccups frequently, the pregnant woman can gently stroke it and it may stop hiccuping after a few minutes. If the hiccups are too frequent and do not work after stroking, the pregnant woman can change her position and the fetus may stop hiccuping. Therefore, fetal hiccups are a normal phenomenon and there is no need to worry too much, as long as the pregnant woman has regular maternity checks, eats nutritious food and follows the doctor’s advice. And you should also do proper exercise during the late pregnancy.
