Sounds like you really like your family
This may be different if you have more that one kid or a different family situation of course.
But still: everything is individual.
I think I should be happy for this: If they'd all been as harmonic as my first one I could easily ended up giving well meant parenting advice telling others "just do as I did, be kind and careful and encouraging and it will sort itself out".
But it doesn’t matter if you’re building software or raising a family - it doesn’t have to be draining. In fact your best work will never show up when it is.
One of my girls is the sweetest, calmest, most peaceful bundle of hugs. The other is a low-sleep, hyper-energetic, demanding chatterbox. She is unyielding and relentless from 5am, every day, and raising her is draining.
I don’t mean “resentful” - we chose this experience and chose not to outsource them to childcare. But some kids are absolutely more work: if your every day is packed 5am-7pm with sales, negotiating, customer service, and all-team workshops, if you get little sleep and no weekends or half-days, year after year, you will be tired. I bootstrapped a software business to 7 figures ARR solo, and raising her is more draining. And more rewarding.
Life is hard for some people! Sorry you have to hear about it in public, but if it's that annoying for you to just hear it, imagine living it!
Whenever I feel sorry for myself it helps to think about my dad who had to live with me as his first child (and I have more siblings that children : )
no argument on that point!
