I don't think you should consider doing it if you don't actually feel any over desire, but it might be worthwhile to take a closer look at that lack of desire. I feel the same way, actually, and I plan on never having children, but I often wonder if that ties into deeper, subconscious issues that might be doing me a disservice.

Also keep in mind that agreeing to have a child out of a sense of obligation or a desire to please your partner could have a detrimental (if unintentional) impact on how you treat the child (especially if something went awry with the original relationship, which can happen).

Not directly related to the book, but a question I've been thinking about lately is: If I don't feel any desire to raise children and I believe it would have a strongly negative impact on my quality of life, are there any reasons why I should still consider doing so? Either moral reasons or self-interested ones (ie. the possibility that I'm wrong about the net utility to me). Another factor is that it's quite likely that I could end up in a long-term relationship with a (female) partner that does want children, and refusing could either result in the end of the relationship or a decrease in the partner's life satisfaction.
