Well, I think mostly, I have an even number. About four hours of labor.
With my first, I had PROM, but my labor did not kick in right away. When it did, it hit full force and was just over four hours.
My second was right at four hours.
My third was just under six hours, but I was traveling and trying to slow things down until we reached our destination (birthing on the side of the highway was just not what I wanted to do), and he was (at that time) my largest baby, a pound more than my first two.
My fourth was four and a half hours.
My fifth was three and a half hours.
My sixth was barely over one hour (VERY quick)
My seventh was five hours, but he was not only posteriour but two pounds more than my others, and weighed in at 9.5 pounds.
So, I just figure, about four hours, about seven to seven and a half pounds and I am pretty sure to be right!
