Baby Sinclair is the youngest member of the Sinclair family in the television series Dinosaurs.

Newly hatched in the premiere episode, "The Mighty Megalosaurus," 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. The baby's relationship with mother Fran Sinclair is more stable and mutually affectionate, but the dinosaur child's wisecracks are also aimed at siblings Robbie and Charlene. Grandmother Ethyl often reads to the child, the pair both rejoicing in Earl's many blunders.

Baby Sinclair is also quite intelligent, being able to speak and spell at a very young age. Never formally named until near the end of the second season, the infant Sinclair is briefly named "Aaagh Aagh I'm Dying You Idiot," the result of the then-Chief Elder keeling over during the official christening. By the episode's end, he has been legally named "Baby Sinclair."

Baby Sinclair celebrated his first birthday in "Switched at Birth". He celebrated his second birthday in "Terrible Twos," where he entered the title stage, causing him to display demonic behavior during the year that he's two. The Sinclairs finally tricked the Baby into thinking he was three years old.

Baby Sinclair was the most heavily marketed of the show's characters, appearing in assorted toys, Happy Meal prizes, and the music video, "I'm the Baby (Gotta Love Me)." He was featured on the box art of most Dinosaurs video releases and was the only character to appear outside of the series, serving as a co-host on the special For Our Children and a cameo in The Dream Is Alive: 20th Anniversary Celebration of Walt Disney World.

Behind the scenes[]

As a hand puppet creation and the smallest member of the show's core regular cast, the character was portrayed by Kevin Clash, with the eyes operated by John Kennedy and the arms by Terri Hardin (replaced by Julianne Buescher for the final season). Clash's voice for Baby at times resembled a more gleefully destructive Elmo.

As of 2014, Baby is the only surviving puppet from Dinosaurs.[1]


  • According to voice actress Candi Milo, Brian Henson asked her to be one of the puppeteers for Baby Sinclair. However, Milo was pregnant at the time, and had to leave the role last minute.[2]
