An upcoming episode of the ABC comedy Modern Family will feature an openly transgender child actor.

In Wednesday's episode, titled A Stereotypical Day, gay couple Cameron (played by Eric Stonestreet) and Mitchell (Jesse Tyler Ferguson) allow their daughter Lily (Aubrey Anderson-Emmons) have a play-date with her friend Tom, who is openly transgender.

Jackson Millarker, 8, plays Tom.

Director Ryan Case called Millarker “wonderful” in an Instagram post.

“One of the many reasons I love being a part of this show,” he captioned a photo of Millarker on set.

According to Variety, Millarker is the first transgender child to appear on a network prime time series.

Florida teen Jazz Jennings, 15, is the star of the TLC reality show I Am Jazz, which follows the transgender teen.
