What's the best way to protect babies from their murderous mothers?

Who doesn’t get upset when they read about a woman who kills her children? There was a time when a mother who killed a child of hers was remembered by name but now it’s become so frequent that it all fades into a huge mash up of deplorable human depravity.

Where I live, there are multiple stories about this sort of thing including recently, a 24 year old who gave birth and proceeded to place her newborn baby in a garbage can and put the lid on top. Luckily the sanitation workers through some sequence of events pulled the lid from the can and discovered the newborn still alive.

A lot of people read stories about that and think “there’s got to be something that prevents this from ever happening again!” So what do we do to minimize the occurrences of mothers killing their children?
