It doesn't matter if you're a stay-at-home mom or a working mom, either role will make you question whether or not you're doing a good enough job as a parent.
"As a stay-at-home mom, I could never feel present with my child," she told HuffPost Canada. "I always felt this odd guilt and longing for selfish development. [Ambitions don't] just disappear when you have a kid."
Reitman has always had a strong work ethic, which is one of the reasons she returned to her acting and directing career just six weeks after giving birth to her second child.
The 37-year-old told HuffPost Canada that she needed something that was "strictly mine, where I can exercise my identity."
But becoming a working mom didn't come without challenges. In the video above, Reitman shares the trials and triumphs of both sides, and how being a working mom can get more complicated as your kids get older.
