Well I was always told it has a lot to do with how big the parents were? But then have heard it has a lot to do with how big the Mum was...

Although my cousin was only about 8Pounds and her partner around 7 and they just had their first baby and he was 10pound 10ounces! He was 2 weeks overdue though.

I was told that my 38 week scan will be to estimate bubs size, so I'll be looking forward to that day.
