I'm not a psychologist and I'm not going to share my experiences because I don't have and I'm not married! But I see around that kids are exactly a little copy of their parents! Are you prepared enough to make a copy of yourself!? Kids speak just like their parent and even use the same word as they do. You don't have to have a kid just because everybody has! You have to make a pivotal plan about that. For example, a friend of mine is a professional pianist and her husband has been her incentive all the time; as I've been invited to their home several times, it's really interesting that their little girl would prefer playing the piano to clash of clans and she reads books instead of watching TV!
James Allen wrote in "As a man thinketh" book: "A man's mind may be likened to a garden, which may be intelligently cultivated or allowed to run wild; but whether cultivated or neglected, it must, and will, bring forth. If no useful seeds are put into it, then an abundance of useless weed seeds will fall therein, and will continue to produce their kind." And I think your kid is like your brain, you can cultivate intelligently or neglect. I don't know how they easily decide to have a baby without having an exact plan. It's full of responsibility of having a baby, parents should be mentally prepared at the first place. I mean they should prepare themselves by working on themselves for years and years with the mindset of having a kid! To be frank, I suffer by seeing a kid's derangement and that's exact cause of their parent's fault!
