Baby Elmo appeared in Sesame Beginnings
Baby Elmo is between 12 and 14 months old. He's a happy, good natured baby who laughs easily and heartily. He is the youngest of the crew but keeps up with the other babies despite his age. He can say words such as "hi" and "dada," and imitate other words he hears, but he doesn't have a word for everything. Baby Elmo is very curious, silly and full of energy. While Elmo is a self-confident baby who enjoys exploring his world, he also checks in with his dad to be sure he's close by.
