A partial answer as I'm on the move atm, and this is just one example, but had a recent discussion on this subject:
National child care policy for ages 0-6
To alleviate the national security issue posed by the declining birth rate, the government is expanding fertility treatment subsidies and building a supportive, friendly environment for pregnancy and childrearing. Amendments to the Early Childhood Education and Care Act are also diversifying service models for childhood education and care, and expediting the addition of slots at public preschools and child care facilities.
Since July 2018, the government has promoted an array of measures to counter declining birth rates such as increasing affordable education and care service capacities, reducing tuition costs, granting childrearing allowances, and raising salaries for child care and education personnel. Through all these measures, the government is throwing its full support behind childrearing households, giving young people the confidence to marry and start a family.
Taiwan has pretty much changed its policies to counter low birth rate.
