According to this blog, UC San Diego and a Japanese company have developed a robot version of a 1-year-old baby.
The robot, called Diego-san, is designed to teach researchers how infants develop motor skills: "In addition to providing clues about how infants interact with the physical world, researchers will also use the robot to explore how babies acquire and refine the ability to use nonverbal communication such as gestures and facial expressions."
The robot has "five-fingered hands capable of holding objects such as plastic bottles." And I'm guessing it doesn't try to deliberately spill milk from those bottles onto the floor!
Also, it seems unlikely that the robot would ever headbutt his owner or kick him in the crotch.
The only question: Is Diego-san cuter than Elliot? You make the call!
