Why Won't Britney Fight for her Babies?

It's enough to make your heart melt when you see the innocent faces of Britney's kids, Sean Preston and Jayden James. Luckily, they are blissfully unaware of the chaos going on around them as they enjoy a ride in their toy cars with their nanny in Tarzana today. It has to be said, Britney and K-Fed have produced really cute off-spring, as our EXCLUSIVE pictures show. It's just a shame that Britney doesn't seem to want to fight for the right to spend more time with her boys.
