I only say the Mother because I feel at present Fathers taking shared leave isn’t as common. But I am not surprised women suffer from PND when they are left to raise a baby for the vast majority of time on their own. It makes me think that maybe the modern nuclear family of two parents and two children doesn’t work, and that we are better how we were in the past as tribes or surrounded by extended family for support. This would also reduce the loneliness experienced by the elderly too.
