Outside of a maternity ward, a young man and woman are bent over a phone. A few minutes ago, a nurse beckoned them over and ushered them in through a closed door. They came back out smiling. On the phone is the photo of a newborn baby girl. She’s in the Neonatal Intensive Care Unit; these are her parents in the waiting area, and her birth mother, or gestational carrier, is in the ward, getting some much-needed sleep.
