Her predecessor, "Teen Mom" star Amber Portwood was jailed after a physical brawl with her ex-fiance Gary Shirley and charged with domestic battery and neglect of a dependent.
"This is a very interesting twist and very significant that the child has a disability," said Kuriansky. "The rest of the shows focus on misbehaviors and the dysfunction of the girls. That only encourages a lot of girls to misbehave."
Kuriansky, the author of the book, "Generation Sex," said this new narrative may make girls "think twice" about getting pregnant so young. "There are consequences."
Hollywood has too often fostered "pregnancy pacts and wannabees," she said.
"There is nothing glamorous about it," she said. "It means you have to be really responsible and have to be reliable and focus on the child and not yourself," she said. "When you have a child with special needs, you cannot be front and center," she said.
Former Alaska Gov. Sarah Palin became a lightning rod for both teen pregnancy and a child with special needs. Her high schooler daughter Bristol became pregnant during the 2008 presidential campaign.
Palin had also just given birth to her son Trig, who has Down syndrome.
"She made a public statement about how moms have to deal with a special needs child," Kuriansky said of Palin. "She embraced him and became more beloved because of that. She was a real role model for how you can be a mom who can have a life and also be an accepting mother."
Still, Kuriansky said television producers would better serve teenagers by providing opportunities to "process" the bad messages that are so rampant on reality shows.
"Families and parents should watch TV with the kids at any age and process them, to actually watch the shows together," she said. "They could discuss the girls' lives and how they were handling it and even pointing out the good things they do."
