23 Weeks Pregnant
All About Baby
Even if your bowels aren’t quite regular these days, your baby may be settling into a regular routine—more active at night, for instance, while quieter during the day. All of her internal systems are in place, even if they do need more time to mature. Her vestibular system—the area in the brain responsible for sensing movement—is one of the first parts of the brain to mature and it is already actively sensing all your movements. At the same time, Baby’s hearing continues to develop and sharpen. Studies show that infants who are exposed to certain loud noises in the womb (like dog barks or the dryer beeping) are less likely to be startled by them once they are born.
This week marks an important milestone—if Baby were born this week, she would have a chance at survival. According to the March of Dimes, of all babies born at 23 weeks, 25 to 35 percent survive. This number goes up considerably when you add just a couple weeks: roughly 50 to 70 percent of all babies born at 24 to 25 weeks survive. And 90 percent of all babies born at 26 to 27 weeks survive.
