I wouldn't limit it to economics either. Socially children are restricting. If you want to be free to travel, move, leave the house on a whim, etc. then kids will interrupt your plans/logistics.

Large families were your source of farm labor.
Large families were your source of labor because you never given a chance to make a better life for yourself.
Switch to an industrial society. Having children to do raw physical labor competes directly with tractors and a backhoes. But you can acquire other assets and put more resources in upscaling children through education. And wage work means you can send wives and daughters out to make money.
I think it usually takes a society one or two generations to figure that out and act accordingly.
Adding a thing I harp on. Malthusian limits traditionally is thought to apply to just food and disease. But you can extended that to an industrial wage based economy and the resource restrictions still apply just not to food and disease. Industrialization probably results in structural population overshoot.

An example of that is the plots in this essay. Attitudes don't change much plotted by age cohort over time.

Summarize that we've thrown a bunch of historical peasants into an industrial society and they're reacting astutely to the new incentives. But the big change comes from those that grew up in it.
Example Bangladesh fertility rate went from 7 in 1975 to 4 in one generation and dropped to 2 one generation later.
I've found having children the most rewarding thing to have done with my life. And even so, you are right about the costs. "Million dollar baby" is not just a catch-phrase.
Likewise, sure things like nannies can be hired to increase my flexibility. But, there’s a noneconomic factor of me just not wanting my kids to be raised by nannies. This requires my presence and engagement.
These are part of a noneconomic value system. In fact, many values like these are at odds with economics. Parents choose to place their values over economics. This might look like passing on a job/promotion that would require a relocation. If you are self aware enough to realize you have these values, you can estimate how becoming a parent will impact your life and choose how important creating a family is to you and if you want to ensure the consequences.
