You hire somebody full-time to fill the position. When the employee comes back from parental leave, either move the new employee or the returning employee into a new position. People ask sometimes why, in capitalism, companies need to grow all the time. Why do company profits have to grow every year? Why can't they just stay at some same, low but healthy level, year after year? Well, this is one of those reasons. When you're constantly growing, then it's not an issue for somebody to come back from parental leave, because there are always new positions opening up. Maybe the person coming back will need to wait an additional week or two for the right position at the company to open up, maybe the person will need some training for a slightly different role. But there will be new spots.
