Most of the other children were taken away after their second birthdays.
This doesn't quite make sense. If this woman only wanted to keep one child, then she shouldn't have been pregnant every single year. She was allowed to keep several children for two years or more, during which she probably have no way of knowing when/if they'd be taken away. Therefore, during that two year period, it makes no sense for her to try to get pregnant again, seeing how she already had a child. If she only wanted one child, she should have a two year break between most of her pregnancies. Seems like she wants more than just to keep one child.
