(AP) — MESA, Ariz. — A baby boom is brewing at a suburban Arizona hospital where 16 intensive care nurses recently discovered they are all pregnant.

The nurses at Banner Desert Medical Center in Mesa outside Phoenix joked Friday they thought there was something in the water when it became clear they were all expecting babies between October and January.

Nurse Rochelle Sherman, nearly eight months along, said: “I don’t think we realized just how many of us were pregnant until we started a Facebook group.”
