Here's a suggestion for increasing fertility rate that I've never heard anyone bring up: government subsidized wholesome milk formula. After the melamine scandal, there has been little trust in Chinese brands in the baby milk department leading to mad dashes to get formula from New Zealand, Australia, etc... Scalping cans of foreign milk powder is big big money in China; I've even heard that mailmen steal large shipments (putting them towards their lost packages allowance) to resell at the risk of losing their jobs. Chinese people abroad who are planning to go back to China keep their trips on the shush because they're scared that if news got out, all of their friends and family members with kids will beg them to bring back cans of milk powder, basically taking up all their luggage space and weight allowance. This is an ugly mess that has to stop.
The CCP should implement national milk formula manufacturing facilities that sell their products at cost to the domestic audience. A (generous) quota needs to be set per registered baby with purchase tickets sent to the parents otherwise you'll get creepy old fucks buying tons of them to drink as replacement to supermarket regular adult milk. These facilities should operate according to strict protocol with no money handling, no profit (all sales go through a separate governmental distribution entity) and no reason to cut costs ever. Everyone from chief manager to janitor is paid by the hour with no relation to product sales and their only function is to churn out huge amounts of high quality baby milk formula.
I recommend bootlegging Kendamil UK's formulas for goat and cow milk for all 3 stages. My wife has scoured the internet for the best in nutrition and lack of weird chemicals and found this to be absolutely unbeatable. She rejected all American, Australian and New Zealand brands that other Chinese go for after analysis of the trace chemicals used in them and found Kendamil (UK version only; US version adds things to F it up) to be number 1. When we brought this to Kazakhstan to accept our baby from the surrogate, the doctors took one look at it and said they'd never seen such an impressive milk formula and they said we must have broke the bank getting it. But they didn't know that it's cheap! Actually only about 40% the price of average US baby formula. Why? Because the UK government subsidizes it. The downside is that they don't want it to leave the country; they want it to serve babies in the UK, so international shipping is not offered. We have to hire a Chinese guy in the UK to buy them and ship them to us in crates of 30, which still, after shipping and his fee, turns out to be about half the price of just buying local US.
