In the new issue of PEOPLE — which is currently on newsstands — Madonna opened up about her rewarding life as a mother to her six children: Leon, Rocco, 17, David, 11, Mercy, 11, and her twins Estere and Stella, 5.
Although Madonna, 59, admits family life can be “complicated,” she maintains that all the challenges are “so worth it.”
“I had this funny notion that when your children get older, they learn to take care of themselves and it gets easier,” Madonna told PEOPLE. “But actually, the older they get, the more challenging it gets — because now they’re becoming adults, and they really need guidance.”
And Madonna is certainly not afraid to offer her guidance, even when it’s in the form of tough love.
“I’m bad-cop, I’m the one that says no,” she adds. “I accept that role. I’m not the popular parent.”
