I've been thinking about this recently. The women in my family (myself, mum, gran and aunt) all say we don't/didn't have a massive urge to have children (although we all utterly adore our kids). Yet some of my friends are really broody and have a massive urge to have more babies.
Why is this?
Does anyone know of any research on what causes this?
I've had a quick google but not come up with much.
