In a recent email, a woman named Renee told me how she and her husband had unsuccessfully spent years trying to start a family. After numerous rounds of in vitro fertilization treatment and several years waiting to adopt, they were exhausted from the ordeal and considering bringing the journey to an end. Knowing that my wife and I had walked a similar path, Renee asked a question. “How do you give up on a dream of parenthood without regretting what might have been?”
