I have a Two year old with another one on the way...
Here is how it went for me...
Went from sorta wanting...
To not wanting....
To wanting....
Had the baby...
First three months I wanted to do like the movie "300" and kick the kid out, give her a stick to defend herself from wolves! It was hard on me...
3 months onwards.... I'm head over heels in love with my daughter (who is a total daddys girl now) and i would never ever want to go back to my life before.
Having kids is hard as HELL!!! Especially the first three months, that's extra hell... I was asking myself why do people do this a second and third time??? Why!!! All a baby does the first three months, is sleep, eat, shit and cry... And cry and cry and cry and cry... And then you cry because you want to throw yourself off of a building. Those first three months you give give give give give and you get absolutely nothing in return.... Then all of a sudden at around the 3-4 month mark something happens, a switch goes off in the baby, and everything you've given comes back to you 10 folds! You get this love that you have never felt before and you fall in love with the baby.... Imagine the one thing your currently love more than anything else, it could be your car, your wife, your mother, Big Ramy, whatever... But imagine that love... And multiply it by 1,000,000,000.... That's the love you start to feel for your child after the first three months and it only grows exponentially from there.
Look, there is nothing wrong with not wanting kids, and if it's not for you is not for you, and that's ok, but speaking from my own experience I went from hating being a father the first three months to never not wanting to be one.
It's hard and its life changing, but if you and your wife are in a good place together and in a stable marriage, you'll be able to do a great job. Just remember, guys are different... You'll never feel ready to be a father, I know I didn't. But I love it!!!
