Disney features lesbian parents Susan and Cheryl on "Good Luck Charlie" (Tumblr)

On Sunday, January 26th, the Disney Channel featured its first ever same sex couple on the network's sitcom "Good Luck Charlie."

As announced this past summer, "Good Luck Charlie" will feature two lesbian moms in its fourth and final season, according to TV Guide. 

The couple is introduced when parents Amy and Bob Duncan (Leigh-Allyn Baker and Eric Allan Kramer) set up a playdate with their daughter Charlie (Mia Talerico) with her friend, who has two mothers. 

Though there are many gay and lesbian couples seen on television today, the kid's channel took extra precautions before featuring the first same sex couple on the network. 

The storyline was developed under the consultancy of child development experts. "Like all Disney Channel programming, it was developed to be relevant to kids and families around the world and to reflect themes of diversity and inclusiveness," a Disney Channel spokesperson said.

Even stars are expressing their support after network's big decision was announced, including Miley Cyrus and Evan Rachel Wood. 

Cyrus tweeted, "I commend Disney for making this step into the light of this generation." 

Bringing a same sex couple onto the television screen is a huge step for Disney, though the couple is not expected to appear in the series after this episode. Known for its family-friendly programs and conservative values, Disney is finally opening up to the progressive changes of this generation, and we're just beginning to see it. 

The Disney Channel is geared towards children and it's only fitting that the family-based sitcoms start including all types of family forms. It's only a matter a time before we see the Disney Channel filled with all sorts of nontraditional families.
