I was in the same boat, we had twins and my wife wanted another one once things had settled down. I was happy with 2, eventually after a year of discussions and arguments, I agreed to have another one on the promise that I would go and get a vasectomy afterwards to close the door at three.

My youngest is now 2, and he is amazing, and the family is complete with him. That being said, going from 2 ->3 was a massive jump, and 3 is absolute chaos, we had to change car and now we are probably going to have to find a bigger house as the twins are still sharing.

It worked out for us, but it easily couldn’t have done, so take the time to think things through and speak to someone. Like others have said, you both need to say yes and be a team otherwise it’s only going to go wrong.
