I had a 9lb and 7lb. With my 7lb i labored 12hrs small tare. With my 9lb i labored 7hr small tare also. I must say both were the same pain just different times:) youll be good mama! Plus i was only 17 and 140lbs with first if that changes anything:)
My mum had my little brother at 10 pound 9.1/2 Oz he was her biggest she said they all hurt the same.
