I was born 6lb 6oz and 47 cm, DD was born 6lb 7 oz and 46cm so we were almost identical in size. DP was 7lb 5oz and about 50cm. If genetics have a link then it would be unlikely that I would have a big baby.

However I kept being told I was having a bigger than average baby due to how big my belly was - but the OB couldn't have been more wrong
