Nope! No interest at all. I definitely don't regret it as a millennial.
I have always been fine with children. I think seeing other people raise them with love and care and real emotional availability is the most heartening thing ever! I've even teared up a little when i see them do it well and with real emotional availability.
I was never interested but i had the question about whether i would with the right partner well into my 20's. I never felt like it was something missing from my life. Now that I'm older i see my friends all across the spectrum about the choice from joy to regret. I am confident, learning about time commitment, cost, and thinking about the liability of a human life, that i would be deep on the regret end. In fact i see not having children as the best choice I've made in life.
I'm thoroughly happy and content being child free.
Complacency is not as bad as direct support. The blood is as much on his hands. Tax payers participated indirectly without their consent.
