Why do you or why don't you want to have children?

I'm posting this out of pure curiosity and to be understanding. I don't mean for this to turn into a feud, if it does I'll take the post down. Whether it's adoption or not, why do you want to be a mother? Why don't you want to be a mother? I'm sure everyone has there different reasonings, feel free to vent in the comments. Lots of love ❤️
