I had one without informed consent, it was very uncomfortable, the OB then went on and refused to attend the birth, and I feel I was pushed into an induction 2 days later.

I am yet to meet an OB who consider 42 weeks to be full term. the fill in OB referred to above told me he routinely induces his patients on their due date or 1 day after (!) and mine won't let you go past 10 days overdue.

I wish I could find one who would!

WRT small sizes, my OB (not the one above, my actual OB) does not believe in u/s to tell the babies size, he used to but had to many occasiion where he had referred an expectant mum for a c/s (he is not a surgeon so doesn't do them himslef, and actively discourages them) for a "big baby" only to have her birth a 6 or 7lb bubba
