Well, the leave should be distributed exactly in the same amount by the persons responsible for the child and should be of compulsory execution by both, exactly as if you have an accident requiring hospitalisation that prevents you from doing any work. That is, taking care of a dependent until a reasonable age for daycare (which, in my opinion should be around at least 8 months) should be an obligation of the society on the well-being of an innocent dependent human being. And if people worry on the economoc side, think that people taking the responsibility of bringing up minors contribute to economic flourishing in additional spending on goods and services and in providing the payers of the debt we are putting on them to pay to sustain our current and future well-being.
