My son's been in the hospital long enough that we know almost all the nurses and doctors. So far, while being here, we have heard the "transition chime" seven times that rings throughout the entire facility. This indicates a birth or death in the hospital. The first one came hours after I heard the intercom: Code Blue. O.R. Adult. Code team dispatched. I hoped it was a birth and not that patient needing resuscitation in the operating room.
UPDATE: As of breakfast time, we heard two more chimes in quick succession. Twins, we hope!
