Obviously no guarantee, but general consensus is that second/subsequent labours tend to be quicker.
I'm intrigued to know how this has translated to the individual stages for people?
My first labour was about 11 hours from first contraction total, however 5 of that was from 8cm to birth (3 hours 8cm to pushing, just under 2 hours actual pushing).
Baby 2 due in the next few weeks so got me thinking!
