> The fathers are looked at negatively if the don’t take some of this time. This isn't just an apriori fact of the culture, but an intentional result of the structure of the leave. 90 days are reserved for each parent (there's an exception for single parents) i.e. if the father doesn't take those 3 months they are lost. Apparently before this policy came into effect, fathers would typically take very little leave. But once there was an incentive to take 3 months they began to take longer periods and split the overall time more evenly. So even though it's part of the culture, it's not impossible to understand how it came to be, and therefore not impossible to replicate elsewhere.
