Baby Sinclair is the youngest member of the Sinclair family in the TV series "Dinosaurs". Baby Sinclair is a precocious, if bratty, child. His catchphrases include "I'm the baby, gotta love me!" and "Not the mama!" The latter is often uttered to his dad, Earl Sinclair, whom the baby repeatedly batters with a frying pan, and generally disdains, especially in the early episodes, though they form a slightly warmer relationship over time.
