Not really. The pushing part got quicker. I had ARM each time though because labour wasn't moving along and was dragging out.
Labour times were roughly 16hrs first time with around an hours pushing - my fault as I was terrified. On and off for 27 hours second time but only ten minutes pushing. And lastly about 7 hours labour and a good 2-3 mins pushing.
Super relaxed last time around though was an upside.
