maybe they meant 13 hours for the entire labour? i was exhausted enough after pushing for 3 hours, i think you would die of exhaustion after 13 hours...not to mention the stress on the baby. after 3 hours of pushing for me the doctor tried vacuum extraction, if that didnt work it was off for a c-sec, so their time limit must be around the 2-3 hour mark. Sounds like a case of chinese whispers..if not i really feel for that lady!
