Good Morning C.!
I have to agree with Katie. Until both of you are 110% sure that you are absolutely done having kids DON'T DO IT!! Find a more temporary form of birth control that both of you can agree on. With a vascetomy, there is no turning back (or if you do turn back, it can be very expensive and very painful for a reversal with no promise of success!)
In my situation, my husband said after 3 kids he was done, finished! So I shared with him that if he knew there was no way he was going to have any more children, then to go and get the "Big V" so that the idea of having any more children couldn't be in my head. A year after he had it done, he came to me and said that he made a big mistake and wished that we could have more children. So we spent thousands of dollars and another procedure reversing the vascetomy.
We were lucky, one side was successfully clear and reconnected. And now we have #4, and are even wondering if we might be blessed with #5 sometime in the future.
There are SO MANY options for birth control. If I could go back in time, I would have definately discouraged the vascetomy more. But we live and learn!!
Good Luck to you! This is definately a decision that requires spouses to be in agreement! Prayer can help :-)
Blessings,
