Here in Nigeria, couples can't work under the same organization unless they keep the marriage a secret from the organization, so for that reason, there is no problem in giving men paternity leave to enjoy the moment with their wives.
Though some fathers will take that for granted but I am sure there are still good fathers out there who would prefer helping their wives and spending time with the new baby to bond with him.
So I didn't see anything wrong in that if fathers too get such leave at work.
