Kate Winslet is enjoying motherhood so much she plans to double her brood. The TITANIC actress already has two children - Mia, six, with ex-husband JIM THREAPLETON, and Joe, three, with her current spouse Sam Mendes - but insists her maternal urges still aren't satisfied. The 31-year-old says, "I'm hoping to have more kids. "I don't know whether (to have) one or two. Oh God, I would love to have more." And Winslet insists the most satisfying part of motherhood is bringing her children up as far away from the Hollywood lifestyle as possible. She says, "Mia said to me the other day in the car, 'Mum, I really love your cooking.' "To me it was a sort of incredibly triumphant moment, the fact that she observed that I do cook their meals. It makes me sound like a domestic freak, but I care very much about my kids' nutrition."
