She's the wide-eyed little Muppet with a big smile who has made it to Sesame Street. Her name is Julia and she has autism.

Julia was first introduced in 2015, playing alongside Elmo and Abby Cadabby, as part of an online-only Digital Storybook story called Sesame Street and Autism: See the Amazing in All Children. Come April, kiddie viewers will be seeing more of Julia when she makes her transition to the live-action fold of the long-running children's show, as revealed in a segment screened Sunday on the US version of 60 Minutes.

Julia will make her debut on Sesame Street, which is screened on the ABC in Australia, with a little help from her friends Elmo and Abby, who will introduce Julia to Big Bird. At first, Julia will be reluctant to shake the big yellow bird's hand.

US 60 Minutes correspondent Lesley Stahl spoke to Big Bird and Elmo about helping adjust to how Julia reacts to situations.
