It's actually cheaper now. the numbers I quote were from when my children were in barnehage many years ago. But remember that is the maximum one would pay, it's graduated according to your income. The rule now is not more than 6% of household income and not more than about 130 USD per month. Also remember that this is eight or more hours per day five days a week in a facility that doesn't only look after your children but also teaches them how to be independent, resilient, social, etc.

Could you get private child care for 300 USD per month?
