My now wife and I became pregnant within 3 months of us meeting, not ideal but 5 yrs on we are married and the kids are growing up fast... We wanted children but ideally would've liked a honeymoon period..
We've rode the endless sleepless nights, which are still on going, every night since august we've been up tending to the toddlers needs/demands, our oldest child, cluster fed and was unsettled at night for 2yrs, the youngest has thankfully been a dream in comparison.. Because of this, yes we do argue, we do bicker, but neither of us dwell on the negatives, and we try to be forgiving..
And we don't keep score, household tasks are done synergistically without a fuss, we both enjoy cooking, I listen to music and she watches her vampire series thingys, no need to turn running the household into some kind of martyrdom..
Her career has taken a different turn and my business has been altered to suit the nursery/school times, everything we plan, we plan with the family in mind...
I love my wife just as much now as I did when we met, we have regular sex and chat daily about anything and everything, we also organise time when we are alone for us just to unplug from being mum and dad even if it's brief.. As a young man I had a jolly good time, I have no regrets and don't wish to be with anyone else and we don't look at others with envious eyes..
Rather than striving for a state of delirious happiness I find being content is much more fulfilling and realistic..
