Owner of a Lonely Heart - S2-E11
Corrected entry: When Dorie is talking to Meredith after giving birth to the quints, she says "If I'd listened to the doctors, I could have had three healthy girls, instead of four who might not live until tomorrow." She had five baby girls. (00:13:50)
Correction: She's referring to fact that only one of her five babies is healthy and has no life threatening medical conditions.
