>know some studies show educated westerners tend to have less kids
This isn't a westerner thing, this is a "literally every economically developed country, and most developing" thing.
Every economically developed country is under replacement rate. A lot of developing countries are dropping dramatically. India went from a rate of 6.something to replacement adjacent over the course of 50 years.
It has absolutely nothing to do with sleep schedules. Birth rate drops as a society becomes more economically developed, and - crucially - women have a greater emphasis on their own education and career.

Disclaimer: below is a hypothesis. Please argue against if know what to say, i like to argue.
Less sleep needed means one can more likely raise a child w/out sleep deprivation. So ones with the trait night have more kids on average. Hence back to my initial statement.
