This is my 4th baby and I'm a bit curious as to preparing myself for the length of birth. My births have been natural and homebirths (& no herbal interventions). My first birth lasted 4 hours and my 3rd was 2 1/2 hours. Child 1 & 2 were born at 37 weeks and child 3 at 39 weeks (although my midwife has no clue how I held it in that long but it was clear in labor I had some anxiety and we think that's why). So if you have 4 children or more- were you labors shorter and did they come earlier? In all honestly I'm not sure I could do shorter then 2 hour birth and its making me a bit nervous!
Re: Any 4th time or more moms?
#2 - 7 hour labor - 40w6d
#3 - 21 hour labor - 40w exactly
#4 - 2 hour labor - 41w6d
#1 and #3 were posterior, which is why they took so much longer.
ETA - no inductions, although I did have my membranes stripped with #4 because I was a two days away from risking out of my HB
With your situation though, since your longest birth was your first baby and it was only 4 hours, I would say you are very lucky and that it is likely that this baby will come fairly quickly. Again, there is no guarantee though. You can definitely help yourself naturally though by walking, squatting, etc...and even look into evening primrose oil (it cannot be taken until you are towards the end though). Best wishes to you!
