Specifically, researchers found that when mothers touched their stomachs fetuses showed “more arm, head, and mouth movements than when the women did nothing or when they spoke to the baby,” Time reported.
“Although it is speculative to suggest, it might well be that the increases in arm movements in response to maternal touch are also directed responses towards the source of the stimulation,” the study’s authors wrote.
To find this, researchers brought 23 healthy pregnant women into a dark room and had them all practice three different behaviors. One behavior had the mothers rub their abdomen, another had the mothers talk to their babies and the last had mothers keep their arms at their side. The researchers tracked the fetuses’ movements with sonography. The first behavior had the most responses from the fetuses.
But this isn’t the only way a child can develop within the womb. A study published in the Proceedings of the National Academy of Sciences earlier this year found that children learn language skills while in the womb when their parents read or talk to them.
The study found that premature babies specifically had a better chance at learning language and reading skills once they were born because their mothers read to them as a fetus, which developed “the auditory fitness necessary to shape the brain for hearing and language development,” according to the study.
“It’s never too early to start reading and talking to your baby,” Dr. Rebekka Levis, an assistant professor at New York Medical College, told The Journal News. “We definitely know that babies can hear their mothers and recognize their voice while in utero.”
A similar study in 2013 found that babies can learn and understand language because of what they hear from their mothers while they’re in the womb, according to WebMD.
Research shows that babies absorb information in the womb during the last 10 weeks of pregnancy, according to WebMD. And babies can recognize their mother’s language over a foreign language right after being born.
But it’s really up to parents to decide what’s best, as long as there is some interaction going on. In fact, Jenna Goudreau of Forbes wrote that any interaction with your child will help your baby become smarter. Babies, even when they’re in the womb, shouldn’t be left to learn on their own, Goudreau wrote.
Pediatrician Anatoly Belilovsky told Goudreau that parents can motivate their children to learn by interacting — whether it’s through reading, talking or touching the stomach — with them when they’re in the womb.
“It’s really the interaction that motivates the child,” Belilovsky said.
“The main message for new moms is that their babies are listening and learning and remembering during the last stages of pregnancy. Their brains do not wait for birth to start absorbing information,” the study’s author, Patricia K. Kuhl, Ph.D., said, according to WebMD.
