Some would call it a miracle, some would call it a 1 in 800,000 chance. Four, naturally conceived quadruplets were delivered at Sarasota Memorial Hospital. In 20 years, the hospital has only ever delivered five sets of quadruplets. All four babies are in the Level III Neonatal Intensive Care Unit but are said to be doing just fine. The parents, Amanda and Kyle Corcoran of Englewood, introduced the kids to the public on Thursday.
