I'm going to tell you the truth that most parents will not tell you either because they lie to themselves to make themselves feel better or because society has a stranglehold on us how WE are supposed to feel about kids, this might sound a hell of a lot pessimistic but read my whole text if you are interested (I am in no way saying this is how the majority of parents feel like but I have had honest conversations with a lot so this text is based on my conversations with men and woman that have kids).
My son was born 2 1/2 years ago 25th of June and it was not a "I am now full filled moment" in some way it felt right and current like, this is what I am supposted to be doing, I believe I could have happily lived another 30 years without kids, but men are rarely ready to have kids.
So lets be honest, lets talk about the bad stuff first...
Yes your life is going to change forever if you want to or not, that little boy or girl will fucking demand your attention 24/7 all the time, yes you will look for ways to be by yourself (the toilet will become your favorite hiding spot) yes you will at times make believe that you have to stay longer at work just so you can surf a few more minutes online without being pestered by your wife or your son to do this or todo that. Weekends will be filled with kids stuff, you will have hardly time to enjoy or relax, as soon as your son or daughter is asleep you will have todo the kitchen and the washing and planing and so forth. That is only very basic stuff, anybody who doesn't have kids cannot imagine the rage you will feel when you finally have a second for yourself and you sit down only to hear that you boy or girl woke up and is crying, you want to fucking hit somebody in the face when you see the ? look on your wifes face like - Its your turn now, the frustration when you are lying in bed and know that THIS WAS your day and you had not a second for yourself is hard to describe, there is no "I put the baby on hold" thats it this is your life and you have exactly two options.
Fight it burn and crash
Embrace your new life and do anything for your family - that means you dont even think about yourself and you learn to love it.
I am currently still fighting it, and I am fighting a loosing battle, I still at times try to find a way "out" just so I can have my 20 min alone, I still at times love to stay up late so I can relax infront of the TV or a good book knowing fair well that next day my guy will be up 07:30 sharp and it will be pain from there on, but I learning slowly that I will have to change more if I want to be a successful father.
Having kids is 90% suffering and 10% pure fucking joy and trust me the 10% will make you happier than you ever have been.
Now since we have the bad stuff out of the way lets talk about the 10% the good stuff.
When you are coming home after a long day work and you have your son running at you throwing his arms around you screaming in joy Papa papa, than pulling your hand to show you what he has done all day, the feeling that there is actually somebody that hasn't learned to lie yet and is truly 100% happy to see you and is amazed every day of new that you came back, that feeling is unbelievable - at least to me.
There are moments when your son looks at you or says something to you and you feel that the world is stopping right there, he is the most wounderful and amazing thing at that time, only parents can feel that way about their own kids an I am 100% sure its probably a trick of nature
but its neverless amazing when it happens.
You will gladly put all your wants aside and rather spend your money on something your son really loves, that comes naturaly and you don't even have to think about it.
Being a father and seeing your son and daughter grow up is amazing, seeing them form their own opinions, stories fears and fun is amazing and worth it.
The most important and awesome thing is this however (and this makes it 100% worthwhile) - Until a certain age - Kid love you unconditionally, its not a fake love or like or anything you have experiensed before, you are for your kid the most amazing thing!! (of course only if you are good to your kid).
Its that love and amazement that they have for you which is making your drunken of love for your kid, you are NOT your kids best friend you are a parent and I strongly believe in strict discipline and have been accused by my mother in law to be too strict but I discipline my child by talking and the occasional naughty step trip, but he has NOT stopped loving me.
Forget the 90% of "suffering" the 10% make it so fucking worth it!!REMEMBER!!
1) You fail as a father if you hit your kids! Its the lowest form of discipline there is, it is a very short term motivator and it never solves anything, talking if done right will have the desired effect, which does not mean that I never felt throwing my son out the window.
2) Kids are 100% in the right to test their borders, they are suppose to fuck up and do it deliberately to find out what they can and cannot do, its is YOUR job as a parent to show them how far they can go before they get "burned".
3) You are your kids best friend by not being their friend but being a parent! You are educating, disciplining and loving them! you don't have a friendship.
4) ALWAYS ALWAYS ALWAYS be consistent - NEVER EVER do the opposite your partner has done!
