mbear, I don't think that wanting a big family is nessescarily about not being happy with the children you have now. There are lots of reasons women want larger families (wanting a big family like they had, wanting a big family because thiers was small, religious beliefs, enjoying motherhood so much they want to keep being a mum over and over, they haven't figured out why it keeps happening, they love thier kids so much that they want to spread the love a bit more just to name a few) and I'm sure that the majority of them have nothing to do with disatisfaction.
