Number 1, was 10hrs from first (agonising) contraction, with two hours of pushing, shoulder dysplasia, haemorrhaging, and ds1 born with an apgar score of 1. Left me with PTSD unfortunately.
Number 2, didn't know I was in labour until about 23:00, born easily at 02:03.
Number 3, proper painful labour was from 02:30 until 05:03, so probably about 30 minutes shorter than number 2.
Number 4, labour started at about 05:30, got painful at about 08:00, left for hospital at 10:30, (12 minute drive), and born at 11:11, so actually slightly longer than number 3, but much more comfortable position, as used a birthing stool. Numbers 2 and 3 were born on the toilet lol.
