any way to discuss having children?

I have a mod about adoption, family relationships, IVF etc. It's basically a better version of anything related to kids and fertility in-game, I believe it's by Lumpinou. You can choose if a sim wants kids or not, and they can change their mind at certain points, but the only option I see with my sims' partner is "Ask if (sim) wants children)". Does anyone know if theres any options I simply haven't seen to try to change your partner's mind if the answer is no? I think it would add some drama. Thanks in advance!
