In 1985, Sesame Street tackled the issue of adoption when they introduced the character of Miles, son of Gordon and Susan. When Roscoe Orman's son Miles was a year old, he revisited the idea. Orman remembers, "Caroll Spinney offhandedly said one day, 'That son of yours is so cute -- he's such a great kid -- we should bring him on the show and let him be your son.' I said that I had suggested something like that years ago but it was shot down. And he said, 'Well, you know, you could even adopt him.' That really started my wheels turning and I mentioned it to [Executive Producer] Dulcy Singer."
The producers were intrigued by the adoption angle, and cast Miles in the role. "The idea is that he'll grow up on the show -- for as long as he wants to," the senior Orman said in 1986. The adoption of Miles was shown in a four part story arch in Episode 2122, 2123, 2124, and 2125. The events of Miles' adoption were also presented in the book Susan and Gordon Adopt a Baby.
In 2006, Sesame Street revisited the issue of adoption with the addition of Marco, the son of Gina. Marco was adopted from Guatemala as a baby. Marco's introduction allowed the Sesame writers to deal with issues of international adoption and non-traditional families.
Executive Producer Carol-Lynn Parente said:
The story of Marco's adoption was addressed in episode 4130, 4131 and 4132. Gina explained adoption stating “There’s a baby who needs love and caring for, and I want to be the person to provide those things.”
