Alanis Morissette is gearing up to welcome her third child with husband Mario “Souleye” Treadway — but her journey to motherhood was nowhere near easy.

In an in-depth new interview with SELF‘s digital issue, the Canadian-born singer opens up about how she and Treadway weren’t sure what their parenting future would look like given their previous heartaches over trying to bring a child into their family. (They are now parents to daughter Onyx Solace, 3, and son Ever Imre, 8½.)
