I remember reading somewhere that the mums diet can effect the size of the baby. It was a newspaper article I think, it was after this massive baby boy was born in Europe somewhere..... He was like 9kg or something crazy and he looked like a 1 year old.

The mother had only eaten carbs and meat during the pregnancy, she herself was huge and the doctors were concerned about how much fat to muscel ratio this baby had been born with.

ANYWAY, so I think it can in extreeme cases. I've heard its down to genetics too, I was a big bubs and so were all my husbands family but my daughter was 7 pound. So our's doesn't really add up to genetics

I can't imagine it being anything else but diet that would effect the size of the child, but honestly I am only going by the fact that what goes in has to go somewhere... I've often wondered if tall people have long babies???

Someone should do a study on this!!! I would be interested!
