Did the stegosaurus care for it's young?

Evidence suggests that the Tyrant lizard king was one of the most nurturing dinosaurs in the animal kingdom, well to its own family anyway. Both parents cared for young, they brought them food, protected them from predators and presumably taught them to hunt. The Tyrannosaurus fossil called "Sue", named after its discoverer Susan Hendrickson showed numerous crippling injuries that did not kill the dinosaur. This suggests that other dinosaurs nursed her back to health by bringing food until 'she' recovered. Otherwise one of those crippling injuries.
