Most #TransformationTuesday photos involve someone getting super fit, or losing crazy amounts of weight. But one woman's #TransformationTuesday photo this week told a different kind of story.Mary Parkinson posted an Instagram showing off a miraculous-looking photo of the progress her infant daughter Grace has made since she was born three months ago, when Parkinson was just 23 weeks pregnant. In the caption, Parkinson says that her daughter weighed just one pound at birth. Today, she weighs five pounds, and has filled out quite a bit."Happy 3 month birthday to this little one!! I can바카라 게임 웹사이트�t believe how much she has grown in such a short time!" Parkinson wrote. "We are so lucky to be your parents!!"Only about half of 1 percent of births happen before the third trimester, which begins at 28 weeks, according to the American College of Obstetricians and Gynecologists. Births that occur between 20 and 25 weeks, six days (like Grace's), are considered periviable births—or, births at the limit of viability, when a fetus could theoretically survive on its own outside the womb. The survival rates for these preemies are low, and many will have severe developmental difficulties. One study, published in 2017 in the New England Journal of Medicine, looked at periviable births from 2000 to 2011. Within that period, survival rates without neurological impairment improved for 23-week-old preemies, from 7 percent to 13 percent. Still, survival demands a high degree of intensive medical intervention, as Parkinson's Instagram feed demonstrates. She started posting pictures of the tiny girl in mid-January: She documented the first time Grace opened her eyes: The first time she got to hold Grace: Her first breastmilk feeding: And baby's first smile: Of course, there have been scary moments, too: "The bad days in the NICU come fast and hit us like a ton of bricks," Parkinson captioned a photo of Grace post-surgery for a perforated bowel. She has also undergone treatment for jaundice, blood transfusions, and many surgeries. Still, at three months old, Grace is off her IVs and out of her incubator, a teeny tiny medical marvel.
