You'd have to make it mandatory leave. The social pressure is still tilted towards women as care givers and men as providers so more men will end up not using the leave. If it becomes mandatory then it's just a baked in rising to every employee, _and_ will probably do better for society to have both parents get time with their children.
I believe some European states solve this by having the state cover ~60% of your wage while on leave so that it's not a giant burden for companies
