As baby inhales, amniotic fluid enters their lungs, causing their developing diaphragm to contract. The result? A tiny case of the hiccups in utero. Several theories exist as to why babies have hiccups in utero. For example, hiccups might:
● Help in lung maturation
● Help the diaphragm to mature fully
● Occur when baby is practising sucking, swallowing and breathing
Various studies have been done to look at why babies have hiccups in the womb. They're not 100 per cent sure why humans get hiccups. Their exact purpose isn't completely understood. We know, however, hiccups are rarely a cause for concern, and it isn't something most pregnant people need to be concerned about. Having hiccups is a normal body reflex, even if we don't know why it happens.
What do fetal hiccups feel like?
Fetal hiccups are quick, repetitive motions that you can tell are definitely coming from your baby. At first, you may think it's a soft kick, but then it'll happen again and again and, yes, again. If you pay close attention, you'll notice that the rhythm mirrors your own hiccups, which are also caused by diaphragm movements — but of course in the grown-up version, instead of amniotic fluid, your hiccup is followed by a rush of air.
How often is normal?
Because every pregnancy is unique, there's no hard and fast rule as to how frequently fetal hiccups should or should not occur. Sometimes they can occur randomly and often, sometimes several times in a day. Still, some babies don't seem to hiccup very much, and that's fine too, as long as you feel other movements in the belly. Hiccups, while in utero are one of the most common fetal movements your baby will make.
That being said, all that 'popping' can be quite distracting, especially if you're trying to get through, say, a work meeting (or a nap!). But as is the case with our own hiccups, there isn't a surefire way to stop baby's hiccups in the womb.
Some suggestions are changing positions, walking around and drinking water might work since any new stimulus encourages baby to shift gears. But the best way to deal with fetal hiccups? Simply embrace them, your baby's hiccups are one of many things that are a part of pregnancy, Eventually, it gets to a point where you won't notice them much. (Now if we could only say the same thing about those constant food cravings.)
How can you be sure the movements you're feeling are normal?
Your tiny human making tiny hiccups might be kinda cute (or kinda distracting, depending on your mood). Trust your instincts. Never hesitate to contact your LMC with questions or concerns. Although fetal hiccups are perfectly normal and healthy for baby, any concerns you have about baby's movements should be addressed immediately.
