Husband doesn’t want anymore kids 😔

We have a 16 month old a 2 month old and I really want a third. My husband doesn’t want anymore kids- the reason is because he wants us to be able to pay for their college 🙄🙄. Of course I would love to be able to pay for their college education butttt I think thats a bad reason to not have another one! Even if we pay for half, I think that’s great! We have 529s for both of our kids, and if one doesn’t use all of theirs, we can roll it into another ones account. So if we have 100k for the oldest and he decides to do community college, or even a SUNY school, we can roll it to the second account, in addition to what she already will have. I see where my husband is coming from but I don’t want to regret not having a third child forever 😫😫. Did anyone have a partner set on 2 kids but change their mind?
