How common are twins?

[SiTay]

So... I'd be interested in knowing because no one really knows the answer.

My husband's dad is a non identical twin and so are my auntie's (my father's sisters) as far as I am aware these are both from the second pregnancy.

I understand that men pass on the "twin-gene" but how likely do we think it will be for me to have twins?

All of my generation have started and finished their families (no more babies planned) apart from 2 of my younger cousins

I think so

Think there are several factors

Overweight
Older mother
Caucasian
Second+ pregnancy
Non id Twins in family

Older mother being.. 35+? Or 40+?

Think it just gets more likely the older you are. I had a nurse saying it to me and I was 32 when my twins were born
