Giving birth to a child is supposed to be one of the happiest occasions in a woman's life, filled with joy and love. 

But for some mothers, the experience ends up being the exact opposite. For women suffering with postpartum depression, having a baby can be nothing short of terrifying.

The stories of women who've suffered with postpartum depression and perinatal mood disorders are the subject of a new documentary titled "When the Bough Breaks."

The film was executive produced and narrated by Brooke Shields and directed by Jamielyn Lippman.
