The film portrays their relationship with complexity and empathy, framing external struggles as societal obstacles rather than inherent aspects of their queer identities. It ultimately affirms the dignity and worth of their love and lives.

The film features trans women as integral members of the queer underworld community in São Paulo, where the story unfolds. While navigating challenging circumstances like sex work, these characters are depicted with an empathetic and raw intimacy. The narrative frames their struggles as external, affirming their presence and worth within the diverse social fabric, resulting in a net positive portrayal.

Baby centers on a young man abandoned by his biological parents who finds connection and belonging through a relationship with an older man and a makeshift community of queer youth on the streets of São Paulo. The narrative frames these street bonds and chosen ties as sources of family and support in place of traditional household structures.
