I've not seen this before.
I'm torn between thinking what lovely children they are - well mannered, well behaved and all clean and dressed appropriately. Then thinking "what on earth compels someone to have 16 children?!"
I do think there must be some psychological void that she needs to fill. And her poor uterus must be wrecked.
I struggle to give my 3 as much time and attention as I'd like, I have no idea how you can do that with so many.
