Nope, sorry. If it helps I think it was a movie rather than a series.
Working on: Author Appeal | Sandbox | Troper WallSorry, that's also not it. The gay couple were bit characters who got the baby at the very end of the movie.
Working on: Author Appeal | Sandbox | Troper WallNot a movie, but You (2018) season 3 ends with Joe leaving his baby son with the token gay couple before faking his death and going off to Europe. One of the husbands was a supporting character throughout the show.
Edited by SynchronicityThat's it! That's the one! I don't know why I remembered it as a movie, but yeah, it was You season 3.

I can only remember this one scene of the work, which I think was a movie, but might not've been, where an orphaned or abandoned child was handed off to a friendly gay couple at the end. I don't remember any other context except that the gay couple were recurring characters.
