I found out recently that my baby has been hiccuping. He has done it a hand full of times the past week or 2. Im 33 weeks. I’m curious as to how that works? Does he suck in amniotic fluid? Do you think it’s reflex? I’m a little confused lol. They say on the internet that it’s “practice” but how ? Like does he just start doing it or does it happen automatically or involuntarily like it happens to us?
