That's one of the first things I thought of when I first heard that she already had six kids at home. Why in the world would anyone that has six kids want more? And, what kind of doctor/clinic would go along with the procedure? I know there are large families like the Duggars, but they didn't go through science to get that many kids. They had fun doing it.
Maybe she had the money up front to pay for it and the facility was greedy enough to agree to help her. It begs to ask who is going to help with all these kids? I know her mother is not happy at all. Will she be raising them or a group of nannies?
I know the laws have changed, but years ago the more kids you had the more money you would receive from the state. So people were purposely having more kids to receive more money. When they changed that and put a limit on how many kids could be claimed the applications for financial help with kids went down. Maybe she was thinking she would get all these donations from companies like Pampers, Evenflo, Little Tykes, etc. Or expecting to be able to have a book or movie deal.
But all in all, I think she's way over her head.
