New dad rocker Rod Stewart refuses to change his baby son's diapers or feed him, according to his brother. Stewart's fiance Penny Lancaster gave birth to the veteran's sixth child last November (05). But the singer is far from a hands-on dad, according to DON STEWART. Rod's older brother claims the couple have a nurse on call throughout the night to feed the eight-month-old, so they don't have to wake up. Don says, "Rod doesn't change nappies or feed ALASTAIR or anything. Rod's not that young anymore so it's quite a thing being a dad. He's 61 and past his best years shall we say. Him and Penny sleep through, and a nanny takes care of Alastair during the night. Penny does feed him during the day though."
