Well, I am puzzled too.
I played the role of a mother, some time ago (my Joshua is 19 years now and Elisha 17). I wanted to give Josh my best. I never played with "dolls", so that time gave me the chance to learn from my own 1st baby (Elisha wasn´t planned, so I was screwed up in raising two kids).
Time passed by and I know HOW I failed. My ex-wife was a GOOD help. She made more money than me, but money NEVER reached "our" expectations, and diapers and ALL that stuff wasn´t cheap (as you now know).
For me, as a father (and half mother) Ha! Ha! I knew how to hug them the way you like (and I never liked having had one brother at the place I knew as "home" and my mother gave us more brothers and a LOVING STRONG sister).
As a family, man and woman have to settle down what ECONOMY the would LIKE to live and what THEY WOULD LIKE TO ENJOY (make it in a written paper, to avoid forgetting that contract of the economy of their marriage).
The moment I asked my ex-wife to take car of babies, followed my resignation from the job I was getting PART of the money my children needed (my ex-wife was -and IS- good to make money).
After some experiences and learning from other people, you´d have your own opinion (and defending position) on that.
Time WILL TELL YOU MISSED important time while you were working in a PC or in a office to make your children look better, to be dressed up and look fine to "your" eyes (because secretly you didn´t want to be LOOKED DOWN). Time will tell you MANY things you´d like to ignore closing your eyes. Of course! Some children may say: "You don´t love me" or "YOU DIDN´T LOVE ME" (My daughter JOY told me that, because her mom pushed her to think that receiving MONEY IS receiving LOVE; but I know how I love and LOVED her (and all).
Inside the room, YOUR HOME, there is a lot of WORK you won´t never be paid (you don´t need to, by the way). Those days you looked after your child watching all those nights to control the fever, his/her coughing (etc) (etc) won´t be paid. Firstly, THEY CAME HERE because you "called" them to be with you (no child has come without a sexual invitation) (only those you have adopted). 2ndly, that job won´t be paid because it is the best job GOD HAS GIVEN A MAN AND HIS WOMAN (Thank YOU, Lord, for that blessing I enjoyed). 3erly, IT WAS THE ONLY WAY I have to know more deeply my father´s feelings, my GRANDMOTHER´S TOILS, how I was raised and, the last, I KNEW MORE ABOUT GOD WHEN BEING ME, as father (not the best, not the worst) and as temporal "mother".
I hope these ideas serve any of you, unpaid labors who love (and loved) their children and those days that are to pass by.
