That's a good question. I don't know. You would have to ask the parliamentarians or the population. I don't know how it might be perceived.
From a purely practical perspective, it raises one question: if a member takes six months of parental leave to take care of his or her child, who will take care of that member's riding? Indeed, it will be necessary to ensure that voters in that riding still have a voice and that the work in the riding is being done. I think this is true for all parliamentarians. None of them wants to see the voters abandoned or less well-served if they take leave.
It's difficult for me to provide a precise answer to the question. I imagine that the answer varies depending on who you ask.
