I think you misinterpreted OP's comment. He meant that having a child completely neutralizes the petty stress of the daily grind because you have something far more important.
For me, having kids amplified the daily grind. I hated leaving in the morning before they got up, and returning after they were in bed. Luckily this is a profession where at least some aspects of the grind are optional, and now I work remotely full-time.
