I didn't want kids. Shit happened. It took about 18 months for me to feel anything for my kid. Those 18 months were a war against sleep deprivation and time deprivation. The wife left a year or two later. Left my kid with me. Single dad shit for the next, well, going on 25 years now. It was the best of times, it was the worst of times. I'm still sick with guilt bringing a kid into this fucked up world, but I love my kid.
This doesn't help you, but I also got a vasectomy about 6 months after he was born. I should have done it earlier. My advice to anyone is, don't have fucking kids. Get a vasectomy ASAP and live your life. Unless you come from big time old money, or get incredibly lucky, kids just add incredible stress and money drain for a minimum of a couple of decades.
I heard a similar news report on PBS a couple weeks ago. Aside from the obvious, and already mentioned, don't have kids. Both for the environment, and to not put your kids through the coming bullshit.
