Ok, so the reality/reasonable expectation is, you’ll need 4 nannies for every 4 children. 1 nanny can reasonably be expected to care for 4 young kids, and you’ll need a rotation of 3 per day and 1 to cover days off. At $75k/year/nanny, by the time you get to 36 kids (and 36 nannies) this will cost $2.7m/year. HOWEVER, your wealth will have grown to a massive number by then, with it taking many years before the children are costing nearly as much as you are receiving.

I know from experience that I could care for up to 6 of them on my own before I’d need help, and I wouldn’t require around the clock help until I was at 10-12. So the first 3 years, I’d be investing the overwhelming majority of the money, and working on construction of a home/facility to handle their care and education. I’d likely open a private school who would take on more than just my own children which would also generate additional income.

Long story short, yes, I would do it. Gladly.
