When do you think it becomes selfish to have another child?

What do you think makes it a selfish decision to have another child?

Obviously there are cut and dry reasons such as not being able to afford to buy food for a further child, and then it's easy. But how do you weigh up benefits and pros and cons of another?

IMVHopinion, having any child at all is a selfish decision in that it is us who want children, not the child asking to be born, IYKWIM?
I am 43, currently expecting DC4, and am aware that some will call me selfish - and I am . As is DH, we are in this together thankfully.

I am not sure whether it can ever be a totally rational decision to try for a child, surely it is more of an emotional desire?
Sorry, I am not putting this very well.
What makes you ask?

I think if you're doing it to fulfill a need in yourself that you know is at the complete detriment to the rest of your family. You know that you can't cope with another but you do it anyway.
