Heidi Montag, a 39-year-old actress and mother-of-two, has explained why co-sleeping with her son, Gunner, turned into an "awful experience." She shared her experience on the April 29 episode of The Hills on the podcast. Montag credits Taking Cara Babies for helping her establish a routine for her sleeping habits and managing her two children. The couple, who have been married since 2009 and have two children, welcomed their first child in October 2017 and will have another in November 2022.
