Ds was 9lb 2, dd was 10lb 4!
I'm only 5ft 5, and both were born vaginally, with a little help from some forceps, 75 hours after my waters broke, after 30 odd hours of active labour, and 4 hours in the final pushing stage, with Ds.
Dd was a two hour water birth with gas and air only, but maybe after Ds, I was a bit stretched. 
my mum was 13 pounds at birth, in the 1940s, I feel very sorry for my grandmother! Big babies run in the family!
