Well my first bub was a 17 hour labour, horrible labour would not come down eventually did.

second was a 4 hour labour very quick hardly even pushed

and my third was 6 hour labour was horrible bled heaps too

Honestly i don't think that it matters what your previous labours were like i think that each one will be different just like the little personality that comes along with it :-)

Hope this helps good luck
