Hi MummaBear79,
I agree with everyone else, as mothers we need to listen more to the little voices, our intuition is usually spot on.
I've had 4 kids and completely understand how exhausting it is, the last stages of pregnancy plus caring for other kids. But being a student midwife and a doula, you must know how important it is for the baby to stay snug and safe for as long as possible, unless "medical reasons" deem otherwise. These reasons are not medical, they are only of benefit to those offering the "available time slot". In reality, your baby could be as much as 4 weeks early on the date that you have been offered.
I know its tough, but try to hang in there.
