What's missing from this is child care costs. My sister, for instance, decided to stay off work (at her own expense) until her child was 18 months because she couldn't afford the daycare costs for infants, which was north of $2000/month. I could see this extension of benefits being a plus for a great deal many families in the same situation.

As for me, personally, my company did not offer new Fathers any top-ups (they did for new Mothers), and my family could not survive on half of my income. I used paid vacation time for paternity leave, it was not feasible any other way, and I am not taking food out of my family's mouth so we can have some feel-good notion of equality. Life happens, nature is not equal and owes you no fairness.
