I think at this point the better question is: why in the past fertility was so high? and I think the reasons were mainly that people _relied_ on their children to grow up and take over the farm and take care of their parents. They were also mortally bored and children are fun. They had them for selfish reasons.
But nowadays? why would you have a child? for a middle class+ family in a developed country, having a child is a 6 figures expense over their lifetime, limits your career, holidays, etc. From a selfish point of view, it doesn't make a lot of sense.
I don't think it's the only explanation but children are, individually, optional so you can, for selfish reasons, do it or not.
