While the spirit of this sentiment is admirable, I think it's also very important to encourage men to take parental leave. Both for the benefit of actually bonding and spending time with their child, but also because it benefits the mother and ultimately family unit as a whole by setting the expectation that both parents will be equally active in childcare.
I don't know the specifics, but I think where I live some portion of parental leave days are allocated specifically to each parent and cannot be transferred. There is also shared parental leave where the days can be allocated as desired, but some are specifically earmarked for each individual parent.
Anecdotally, I've had many coworkers regardless of gender take from a few months to a year off to be with their children, and firmly believe it benefits society and the work environment as a whole for them to be able (and encouraged) to do that.
