I have 3 kids, 1 bio and 2 bonus, and man it's a lot of work. (youngest is technically an adult but de facto...)

As you'll no doubt have learned, fertility has fallen everywhere in the developed world, both in countries with shit welfare for parents (Italy) and quite good (the Nordics). Realistically, the only way to reverse this is to enable draconian abortion laws coupled with a systematic repression of sex ed and contraception. Of course this is congruent with today's fascists' goals...
