Little ones spend nine months growing in the womb and what they experience in there is still a bit of a mystery. It’s hard for doctors to test what babies are doing and learning as they hang out inside mom.
Here's a sneak peek at what's happening:
Moving around: Experts say kicking and other activity can be a reaction to mom eating or changing positions; or it might happen just because the baby feels like moving around.
Learning: The outside world affects little ones in other ways.
Babies appear to recognize nursery rhymes even before they are born, according to a recent study published in the journal "Infant Behavior and Development." University of Florida researchers asked pregnant women in their third trimester to read classic verses to their bellies twice a day for several weeks.
In utero, the baby's heart rate slowed when the rhyme was read by mom and continued to lower even when a stranger’s voice took over story time a few weeks later.
Listening: Hearing is a sense that develops early in the process.
A baby’s ears are fully formed about halfway through pregnancy, which means children may know their mom’s voice by the time they're born.
“Prenatally, it’s got this extra boost by the fact that it’s coming in through the whole body,” said Dr. Christine Moon, an affiliate associate professor at the University of Washington who studies babies’ voice recognition. She found that when hours-old newborns are given a pacifier to suck on while hearing a recording of their mother's voice, they will suck faster, suggesting familiarity.
Taste and smell: These sensory systems develop around the 20th week of pregnancy, allowing the baby to enjoy some of mom's cravings through nutrients in the womb and maybe even leading to some future favorite foods.
Researchers have found that mothers who consistently ate carrots during the end of their pregnancy had babies who enjoyed that taste more than babies whose mothers hadn’t shared the same diet.
Sight: This is the last sense to mature, though some new evidence suggests babies are able to differentiate between light and dark in the womb.
But if you're an expectant parent, that doesn't mean you need to provide extra stimulation in order for your little one to thrive in mom's belly.
