I'm going to weigh in with something I've said before in some other thread - wanting a child is like wanting a Ferrari. It's pretty much entirely for display purposes. It's a way of assuring the self that it will live on, and not be forgotten. And hopefully, a chance to mould a better version.
While there's nothing there that can be called wrong (after all, the said extension of self doesn't exist yet), I still find it to be a way of simply passing down bad traits, in most cases. Maybe this is down to the part of the world I live in, but all I see in family trees is the tendency to create a perpetual chain of servitude. You are born, and you grow up being moulded into what your parents need you to be. Then, you pay them back, and if you're unhappy, you're supposed to have kids so that you can have a second shot at life, via proxy. Again, there really is no moral framework that can properly argue against this, it's just something I am not interested in participating in.
@Mr2005 I wish you all the luck in the world in having a child, if that's what you feel would be best for you and/or your partner. I would still request you to try and not let the child become a way to relive your life. Don't try to force them to become an ideal that you have in your head... That's kinda what got me here.
