I love having a child, but I'm one of the rare types of young people who actually WANTED to have a child so that needs to be weighed.
Daughter is almost 11 months now and sweet as heck. Super alert, super playful and the most adorable child I've ever seen (I know, everyone says the same thing...). Circumstances would probably be different if she was a whoopsie-baby, but even so I think I'd still enjoy being a father just as much.
Spent almost the last 6 months being a stay-at-home dad while my wife wraps up her nursing degree. It's difficult, especially now that I'm picking up courses and heading into pharmacy or medicine myself. We still plan on having another couple of children, but I imagine it being easier once the wife's making big bucks as I have an easier time focusing on academics without being distracted as easily. More financial independence will mean it'll be easier to enjoy parenthood even more. I wouldn't trade it for the world. Nothing's invigorated me and given me an appreciation and lust for life than being a parent. It drives me to be the best person I could be. And I hope that I can become an inspiration to my children or at least die trying my hardest.
Totally appreciate people not wanting to have kids. Some don't make the connection. I know a few dads who either have their first or even second or third child. Some of them don't make "the connection" with their child. That sounds foreign to me because I want to murder anything that causes my girl any sort of discomfort, but for others they just don't bond the same way. I pity them and don't think they're stupid or selfish at all. Children occupy a huge portion of your life and you're either entirely committed or you're not. It's not for everyone and I don't think people are evil if they don't feel head over heels for children.
