Honestly, the trick will be to get every new mother to take it by default. Everyone always thinks they're fine... until they're not. Feeling overwhelmed and 'blue' is very common, it's the postpartum psychosis that is the problem and there is no way to tell whether someone is just going to get tearful or drown their baby. So, I think it should just be routine for mom to take this for a few weeks postpartum.
