It's clear that her fans support her belief that the stigma attached to mothers who openly breastfeed is unhealthy. Sarah co-founded the website, Your Zen Mama, with fellow actress Teresa Palmer. The women created YZM to be an "all encompassing space to build a community of parents and caregivers discussing the comedy, beauty, and complexity of pregnancy and parenthood."

Sarah also has a three-year-old son named Wyatt with her husband Eric Christian Olsen, 39. The couple tied the knot in Wyoming in 2012.
