I don't mean to be critical, but if your insider works in the hospital, this person should not be giving any information whatsoever out about Mary. It's highly confidential info as with any patient. If your insider is found out about the leaking of confidential info of any patient, he/she could be fired and may be subject of a lawsuit.
I'm anxious for the babies to arrive safe and sound, but your inside person shouldn't be talking. I know I've worked in hospitals all my adult life and when your hired, confidentiality is in your written contract and you can be fired for breaching it. Before anyone asks, if Mary was my patient, I would keep my mouth shut, it's her privacy just like other patients.
