Ah, gotcha. And that depends. If the number of pregnancies/births is lower than their desired number of children (which you can again ask about in the Talk menu), they will continue to Consent. If the number goes past how many children they want, they have a chance to no longer want kids (and you’ll have to ask again).
When they actually give birth (ie: the childbirth panel) they will say something along the lines of “I don’t think I want to have any more kids”.
