This amazing picture of second trimester triplets in the womb is part of a series of 4D ultrasound scans created for a National Geographic special. Sometimes pictures truly do speak louder than words, and who can doubt that a pregnant woman seeing a picture like this of her own baby would bond even more than she might otherwise with the moving bump in her tummy. When social marketers promote prenatal care and healthy habits for mothers-to-be (e.g., not smoking or drinking alcohol, eating nutritiously, etc.), pictures like these can help to make that abstract baby more real. If the technology gets to the point that everybody’s 18-week ultrasound is this detailed (and not just those who can go to the boutique ultrasound storefronts), I think we will see women being even more conscientious about how well they take care of themselves (and thereby their babies) during pregnancy.

This reminds me of those pictures of earth from space in the 1960s and 1970s, which did so much to change the way we viewed the planet and each other.
