My first obstetrician guessed DS would be 8lb 8oz just by feeling my tummy. DS was 8lb 7oz. I was impressed. (3.83kg).

Second obstetrician guessed that DD would be about the same as DS. She was 9lb7oz - 4.25kg.

This time around I have had an ultrasound to estimate the weight because obstetrician has been a bit twitchy about me having an even bigger baby this time. Ultrasound said that as of 36 weeks baby was 3.3kgs and so they are telling me an average size baby this time and I don't know what to think! I do "feel" smaller but then I was never huge with the other two either, everybody was shocked when they saw the size of DD.

I have to say that the concern about another 4kg baby has left me a bit nonplussed because honestly, DD's birth was just fantastic. No drugs at all, I was just in the shower till they made me get out and push - 15 minutes, only 3 tiny little stitches, and I left the hospital after 2 days.

No gestational diabetes.

I wouldn't let your ob put you off. Just do your research on labour positions, breathing, coping techniques etc etc. I'm surprised he isn't saying that he will at least let you attempt labour. My first ob said there was only one way to find out if a baby was too big and that was to let the mother go into labour first. The reaction of other people when they hear how big DD was is always but I can honestly say I really didn't think it was that bad.
