I had Tristan at 34+3 and he was 6lb 13oz (3090 grams) I spent the first few days after birth wondering how big he would have been should I have made full term
Kayla was born at 34wks (33+5 according to hospital.. pfft - what do they know lol) and she was 3.5kg (7lb14oz). I too wonder how big she would have been should she have been full term! Think my body knew she was big enough and booted her out!

I was never measured, nor was a guesstimate ever made of her size. My OB had hinted at her being a big baby tho, but never in so many words. Just that he double checked my file to make sure I didn't have GD. I could tell he was looking for why the baby was so big, but he literally stopped himself short of saying she was a big baby LOL.

I agree with the others, don't rely so heavily on those measurements that you feel pressured to do anything you're not comfortable with.

Read up on birthing positions that open up that pelvis. Remember that women birth big babies every day.
