Right, but at least here in Norway the rule[1] is that in kindergartens there should be one adult per three kids under 3 years old, and one adult per 6 kids above three years old. There's also requirements for pedagogical staffing so it works out to be a bit more than that, but not much.
Following such a scheme, on average you free up more workers by sending kids to kindergarten.
