I am 30 years old already with a 7 and 5 year old. I am 7wks and 4dys, I will be 31 when this baby is born, is labor harder on your body after 30????? Also does each labor really get shorter, had 18 hour with son and 1 hour and 39 min with 2nd child and worried i wnt make it to the hospital with this one.
