When Does a Baby Hiccup in the Womb
Babies in the womb behave in ways that are startlingly similar to their behaviors outside the womb. Reverse to what some expectant parents might believe, the womb isn't just a place where a baby grows in at-home, quiet twilight isolation. Babies in the womb are busy. They poop, pee, experience sights and sounds, and practice skills they'll employ after birth, like sucking their thumb and crying. At that place'south even testify babies could already be learning before coming into the world.
"Babies can practise annihilation in the womb that we practice as adults," explains OB/GYN Dr. Kecia Gaither, Director of Perinatal Services at NYC Health + Hospitals/Lincoln. That doesn't mean that a fetus is writing a peachy American novel, but it does mean that the bones biological processes are up and running. Here are some of the more than intriguing and counterintuitive.
Babies Pee in the Womb
"We all developed in a sack of our ain urine," Gaither says. "That surprises a lot of parents." She notes that much of the amniotic fluid in the amniotic sack where a infant develops is composed of fetal urine. That'southward because the amniotic fluid basically circulates through the developing fetus, which allows the organs to develop their specific abilities.
A fetus gulps in amniotic fluid and it travels through the gut, the kidneys and bladder and eventually back out into the amniotic sack as urine. Merely Gaither notes that parents shouldn't be too squeamish about this fact. "It'southward sterile," she says.
Babies Poop in the Womb
What goes in, must come out. And fetuses do excrete a solid-ish waste matter in the womb called meconium. Information technology's non poop every bit adults commonly know it. In texture, it's more like tar. It doesn't pose any danger to the fetus unless it is breathed in during nascence, a rare occurrence called meconium aspiration syndrome which occurs in five to 10 percentage of childbirths, particularly when a baby is past due.
Parents will get to know meconium themselves. It'south the waste matter that fills a newborn'southward first few diapers. But don't dread it too much. While meconium can be sticky and difficult to wipe off it is mercifully not smelly, thanks in function to the sterility of amniotic fluid. Don't get used to information technology though.
Babies Breathe in the Womb (Sort of)
The manner babies "breathe" in the womb is completely unrelated to how they get oxygen and release carbon dioxide from their bloodstream as they grow. That process happens via the umbilical cord and placenta. Mothers are essentially inhaling and exhaling for two. However, a fetus does practice the physical movements of animate.
Gaither notes that when infants bring amniotic fluid into their bodies, a portion is pulled into the lungs where it helps develop the biological structures that will be essential for breathing on their own. That process of bringing amniotic fluid into the lungs looks an atrocious lot like breathing.
Babies Hiccup in the Womb
If a fetus is making the motions of breathing, while ingesting amniotic fluid, it would stand to reason that they would hiccup. Hiccups are a biological reflex that occur in concert with lung evolution. For moms, they may feel like repetitive bounces or jerks. Hiccups in the womb are completely normal and can sometimes be felt more than one time a twenty-four hour period beginning effectually the sixth calendar month of pregnancy. They become more rare after 32 weeks.
Babies Suck Their Thumb in the Womb
Plenty of parents take been delighted and surprised after high definition ultrasounds reveal their unborn baby with their pollex in the gob. There'south cipher to advise that thumb sucking in the womb is conscious beliefs. However, when yous combine the power to move arms and legs, a developing sucking reflex, and cramped quarters, information technology makes sense that should the thumb bump into mouth, it volition exist sucked.
Babies Can See in the Womb
A 2022 report out of Lancaster University in the U.k. for that a fetus in the third trimester will track lights shone into the womb. Fantastically, researchers found that babies in the womb had a preference for lights that were in the pattern of a human confront, and showed that preference at a rate similar to newborns.
While in that location's no mode for a baby to encounter anyone'due south face up in the dimness of the womb, the study does bear witness that even before nascency, babies are hardwired to find facelike shapes to pay attending to. So practice making interesting faces earlier they arrive.
Babies Tin (Probably) Learn and Remember in the Womb
There have been many studies that advise that a fetus exposed to stimuli in the womb volition be familiar with those same stimuli outside of the womb. Play the same song for a fetus during pregnancy and you can look your baby will exhibit a calmness and recognition of the same song after they are born. Brand that song a lullaby and you lot may fifty-fifty get your baby to sleep easier.
But one 2022 study funded by the National Science Foundation suggests that babies can learn, remember and respond earlier they are born. Written report participant moms-to-be read a plant nursery rhyme aloud over a period of several weeks. Fetal middle charge per unit was monitored to mensurate the baby's familiarity with the rhyme — a decreased heart rate signaling that the fetus was not being exposed to anything novel. At 38 weeks, study participants exposed their fetus to a recording of the nursery rhyme past a female person stranger. Despite having not heard the rhyme from their mother for a period of 4 weeks, fetal middle-rates slowed, indicating that the baby in the womb remembered the rhyme. The fetuses who had non been exposed to the story before saw the contrary effect — increased center rate indicating the rhyme was new and novel.
So equally a baby grows, it's important for parents to remember that the womb isn't the quiet gestational chamber they might think. A baby is pretty active in the womb, practicing all the skillful things they'll exercise later on their born — and perhaps even taking some mental notes about what to expect from the outside world.
