100%. I had to drop about half my interests and hobbies after having kids, to remain sane (trying to continue juggling all of them was plainly just going to lead to never doing anything, really), and adjust all the others to fit better with kid-having.

If you can't hire "help", it's like losing 20 waking hours from your week, at least, just for the not-at-all fun or "quality time" parts of having a kid (extra housekeeping [so... very much more], extra shopping, taxiing the kids places, extra household planning, basic hygiene stuff, et c). And on top of that you need to spend "fun" time with them, too, like that part may be more enjoyable but it's non-optional and a lot of stuff an adult might want to do or accomplish doesn't integrate well with it.

Slice ~30-40 hours off the waking hours of both adults in the household, on top of 45-50 hours of work and other stuff necessary for work (commute, et c.) and... yeah this is just bullshit if you can't hire help.

[EDIT] Oh, this reminds me of a certain genre of LinkedIn post that I especially hate: the CEO bragging about how they find time for family despite having five jobs. The real answer to this mystery is that zero of those jobs are actually full-time work, and, the part they never mention, is that they pay others to do tens of hours of work per week that normal people have to do themselves, like lawn care, housekeeping, fixing broken shit in their house, shopping, keeping track of and making appointments and such, et c.

This. Don't forget that HN is extremely biased towards High income/net worth viewpoints. The reality for a lot of parents is much worse than most commenters here
