No prediction of weight, but at my 20 week scan I was told that this ones head size was 95 percentile but not out of proportion with the rest of him, so guess that means is big all over. I am expecting a big bub with big head, based on DD and the fact DH and I both have big heads, and my fundal height measurements, but I want a big baby little ones scare me, and with the birth what will be will be am sure if he is in the right position all will be fine. Everything I have read suggests is position rather than size that has more impact (DD forehead posterior presentation leading to e-csection) and so a big baby in a good position can give a better outcome than a smaller baby in a bad position. I am sure I was also told that big heads can be a good thing, something to do with the pressure of the head on the cervix causing efficient dilation or something. I would also be very surprised if all babies grow at a uniform rate over the last 20 weeks (which they would need to give an accurate prediction of size) would think is like people varying rates of growth depending on genetics and other things.
