An Easton woman gave birth yesterday in the back of an ambulance.  Easton EMS received a 911 call yesterday morning from the expecting mother.  Police helped EMS load her safely into the ambulance while the fire fighters prepared the ambulance for transport.  With contractions minutes apart, the ambulance picked up the paramedic en route to the hospital, but before they reached their destination a baby boy made his appearance in the world.  EMS officials say it was a huge moral booster for the staff that has seen so much suffering  over that last few months.
