 The basic concept is you're not allowed to take birth control unless you get a rabbi's dispensation. Meaning if you go to a rabbi and you say, look, I can't handle it anymore. My body needs a break, blah, blah, blah. Technically, the rabbi can give you two years in between children to kind of not have babies. However, it's so looked down upon and it's so embarrassing and humiliating like, oh, you couldn't manage it.
