The 43-year-old, who has sons Kingston, six, and four-year-old Zuma with husband Gavin Rossdale, said she struggled with her home life and being a devoted mother, reported Daily Express.
"I would be up all night because my second baby didn't sleep, and he had a lot of ear infections. Then I'd wake up in the morning and do my workout, which I always felt I had to do, and then meetings for my three clothing lines, and then hang out with my kids, take them to preschool.
"I'm going to go to the studio and try to write a record. I'd sit on the couch [with my band mates] and be like, 'Let's do this now, because I'm missing time with the kids. I could be having dinner with them and putting them to bed.' It was really hard," she said.
