Baby Cookie Monster appears in the Sesame Beginnings series consisting of direct-to-home-video releases and related media. Baby Cookie's tastes are generally similar to that of the more grown-up Cookie Monster: he loves cookies, and parties as well. Baby Cookie Monster is 16 months old, and is primarily seen with his Grandma in these appearances.
Outside of Sesame Beginnings, Cookie Monster has also been seen as a baby in "The First Time Me Eat Cookie".
Baby Cookie Monster is the only baby not to be voiced by the same actor as his older counterpart.
