Mental health difficulties after birth are a global problem and maternal mental health is one of the Millennium goals set by the United Nations. /http://www.un.org/millenniumgoals/
As such I try to keep a eye out for useful resources across the globe. In the light of recent progress in the US for maternal mental health I came across a blog by Lauren Hale, who is based in Georgia.
She links to some useful resources especially for Dads.
