So practice making interesting faces before they arrive. While there’s no way for a baby to see anyone’s face in the dimness of the womb, the study does show that even before birth, babies are hardwired to find facelike shapes to pay attention to. Fantastically, researchers found that babies in the womb had a preference for lights that were in the pattern of a human face, and showed that preference at a rate similar to newborns. Babies Can See in the WombĪ 2017 study out of Lancaster University in the UK for that a fetus in the third trimester will track lights shone into the womb. However, when you combine the ability to move arms and legs, a developing sucking reflex, and cramped quarters, it makes sense that should the thumb bump into mouth, it will be sucked. There’s nothing to suggest that thumb sucking in the womb is conscious behavior. Plenty of parents have been delighted and surprised after high definition ultrasounds reveal their unborn baby with their thumb in the gob. Hiccups in the womb are completely normal and can sometimes be felt more than once a day beginning around the sixth month of pregnancy. For moms, they may feel like repetitive bounces or jerks. Hiccups are a biological reflex that occur in concert with lung development. If a fetus is making the motions of breathing, while ingesting amniotic fluid, it would stand to reason that they would hiccup. That process of bringing amniotic fluid into the lungs looks an awful lot like breathing.
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. However, a fetus does practice the physical movements of breathing. Mothers are essentially inhaling and exhaling for two. That process happens via the umbilical cord and placenta. The way babies “breathe” in the womb is completely unrelated to how they get oxygen and release carbon dioxide from their bloodstream as they grow. Story continues Babies Breathe in the Womb (Sort of) That’s because the amniotic fluid basically circulates through the developing fetus, which allows the organs to develop their specific abilities.
“That surprises a lot of parents.” She notes that much of the amniotic fluid in the amniotic sack where a baby develops is composed of fetal urine. “We all developed in a sack of our own urine,” Gaither says. Here are some of the more intriguing and counterintuitive. That doesn’t mean that a fetus is writing a great American novel, but it does mean that the basic biological processes are up and running. Kecia Gaither, Director of Perinatal Services at NYC Health + Hospitals/Lincoln. “Babies can do anything in the womb that we do as adults,” explains OB/GYN Dr. There’s even evidence babies could already be learning before coming into the world. They poop, pee, experience sights and sounds, and practice skills they’ll use after birth, like sucking their thumb and crying. Contrary to what some expectant parents might believe, the womb isn’t just a place where a baby grows in calm, quiet twilight isolation. Babies in the womb behave in ways that are startlingly similar to their behaviors outside the womb.
