I know a number who have done so gladly until they and their husbands are too tired to make more. And several of them, by modern, secular American standards, "can't afford" the ones they have. Doesn't matter. Children are gifts from God and they are accepted for who they are.
Once a catholic woman is too old to become pregnant, does sex between her and her husband become sinful?
“And several of them, by modern, secular American standards, “can’t afford” the ones they have.”
So who supports them?
“Doesn’t matter.”
Oh yes it does.
