my hot take is that becoming a parents is your biological "becoming an adult switch" you can feel that something in your body is shifting and because many people today decide against kids, they kinda never grow up so some end up being 40-50yo children btw not looking down on that at all just sharing what it feels like for me

btw I do believe this switch pretty much makes you better at most things better leader, less bullshit, more clarity of what you want etc
