Honestly the whole thing was much harder/worse for my wife. I'm a bit autistic so, was a bit unemotional/logical about it all. She was a mess the whole time.
I wasn't sure about being a dad. Now, I'd kill anyone who tried to take it away from me. I never realized the full gamet of life experience being a dad brought. How much love you can have for these little critters. I'm 40 now. My oldest is 3 and youngest 1.5. I've had a lot of depression in my life, and a lot of things I've regretted. My kids will never be one of those.
Knowing what I know, and never having them, definitely would be the biggest regret ever. Sure, some people aren't meant for parenthood, I see it all the time. We have relatives who neglect their kids, or let them ride a 4-wheeler without a helmet (to the point where one is in a wheel chair and is mentally challenged... I used to play video games w/ him when he was 11, now its hard to keep a conversation going). So, if you think you would be neglectful and not a good parent then don't be one. The world has enough shitty ones.
But if you think for a moment you could be a good dad, then you'll never realize the amount of growing you'll go through once you become one, the perspective you'll gain. It's truly life changing.
Edit: and it has nothing to do with our income. We're both 6 figure engineers.
I recommend it, it makes your life chaotic and costs money, but its the best thing in the world, you'll never be the same. Think about how you'd be in your 50's or later with no kids, I don't know anyone that said they're glad they didn't have kids, but I do know a few that are sad they didn't. Just a random internet guys opinion.
