It's a position of antinatalism. Antinatalist philosophy roughly claims that sentient beings are harmed when they are brought into existence, and it is therefore wrong to procreate.
I think everyone ought to consider this philosophy / argument before having children - as to recognize the severity of the act. At the very least, not having children should be the default, and to have a child one needs to think thoroughly and clearly, and to have a clear reason in mind when saying "yes", as it's one of the most important decisions in one's life.
