Sara Ellington thinks you’re a good mom.

“We didn’t know we were writing a book at the time,” says Sara. Her book, “The Mommy Chronicles,” is a compilation of daily emails she exchanged with co-author Stephanie Triplett after they learned they were both pregnant. It’s an honest account of motherhood today: Sara struggled with breastfeeding and postpartum depression but decided to be a stay-at-home mom, while Stephanie wrestled with her decision to return to work but breastfed with ease.

“We had two completely different experiences,” says Sara. Their stories struck a chord with mothers and non-mothers alike—the pair went on to co-host a weekly radio show, and a film, called “The Mommy Movie,” is in the works.

“Writing a book, when it’s your life, you feel sort of narcissistic. You wonder, ‘Is anyone going to think this is interesting or funny?’ When a reader responds, for me, especially the women who had postpartum depression, that’s so rewarding,” says Sara. “I feel we are really far away from where we need to be in terms of respect for mothers. It’s such a hugely important job.”
