well, the t- rex did because it needed to care for its other young.
No type of mother dinosaur ate its own babies, although a few may have eaten the young of others from their species. The misconception comes from the misidentification of lizard remains in the stomach of a Coelophysis. Because the lizard bones were thought to be infant Coelophysis, people thought they were cannibalistic. The error has since been corrected.

Many species of dinosaur are believed to have nurtured their young. Dinosaurs that certainly raised their young include Maiasaura, Oviraptor, Massospondylus, and most birds (which are a subgroup of dinosaur).
Plateosaurus was an herbivore, which means that they ate plants.
