Actress Ava Amurri Martino has opened up about her battle with post-partum depression after confessing she spent a week in bed following the birth of her first child Marlow Mae this summer (14).

Susan Sarandon's daughter underwent a marathon 36-hour delivery, and then spent a month trying to come to terms with the stresses and strains of becoming a new mum.

She tells, "The first week was really intense. I was not expecting how hard it was... I didn't leave my bedroom, let alone go downstairs.

"My mom would bring stuff up for me to eat and I really just stayed in bed with Marlowe nursing."
