Morissette has been candid about motherhood since first becoming a parent, opening up to PEOPLE in September 2017 about the devastating postpartum depression she suffered after the births of both her children.

“There are days I’m debilitated to the point where I can barely move,” the Grammy winner said at the time. “As a kid, I imagined having children and being with an amazing partner. This is a whole other wrench I didn’t anticipate.”

The musician also refused to stay silent about her struggle with PPD. “The stigma remains in a really big way,” Morissette said.

“There’s this version of eye contact that I have with women who have been through postpartum depression where it’s this silent, ‘Oh my God, I love you. I’m so sorry.’ “
