Amanda Peet, the outspoken advocate for getting children vaccinated, has gone public on another motherhood issue — postpartum depression. The actress told Gotham magazine that she suffered a bout after giving birth to 18-month-old daughter Frankie. She said:

And [after I gave birth] I had a fairly serious postpartum depression. I think it was because I had a really euphoric pregnancy.

The 36-year-old actress is the latest in a growing group of celebmamas, which includes Brooke Shields and Gwyneth Paltrow, who have been vocal with their struggle. She believes that mothers feel shame when they don't experience bliss after giving birth.
