One of my Facebook friends, Janel Atlas (editor of the anthology They Were Still Born: Personal Stories about Stillbirth, in which an essay about Ben's death will appear) (now available for pre-order on Amazon! And Barnes & Noble!) posted a link to this interesting article about how fetal cells remain in the mother's body for years after the baby's delivery.
Dr. Diana Bianchi (not to be confused with the Diana Bianchi who broke up Christie Brinkley's marriage to Peter Cook) is a pediatrician and researcher in fetal cell migration. She discovered, a decade ago, that fetal cells remain in a mother's body for many years, perhaps forever, after a pregnancy, whether that pregnancy is full-term or not. These cells somehow assist in healing the body, providing a therapeutic effect, migrating to the site of an injury or source of an illness, doing what they can to fix the problem.
They're still here, our babies. Still with us, still residing in our bodies. Not them, but part of them. And that makes me feel much differently about losing my son.
