Marco

Marco Jefferson is Gina's son on Sesame Street. He was adopted from Guatemala as a baby in 2006 (beginning with Episode 4130).

Marco's introduction allowed the Sesame writers to deal with issues of international adoption and non-traditional families.

Marco was the fourth major baby/child added to the cast, after Miles, Gaby and Curly Bear, and the second adopted child after Miles.

Executive Producer Carol-Lynn Parente explained the inspiration for the storyline:

“Statistics show that almost a third of children are being raised in single parent households, so we felt it was important to reflect this growing family trend on our 'Street'. By using an adoption storyline to represent the single family household, it also gives us a chance to model yet another definition of what a family is.”

In his debut episode, Marco was played by adopted Guatemalan twins, Ashlynn and Caleb. For Season 38, Marco was played by a 10 month old boy, Matthew.
