Three in the Bed is a traditional nursery rhyme and counting song that predates television, built around children rolling over in bed until one falls out each verse. Its appearance in Bluey, the Australian animated series about a Blue Heeler family that began in 2018, gave the rhyme a new audience of parents and young fans. Clips of the Bluey version circulate online as a light family meme, shared for sleepovers, sibling moments and crowded bed jokes, keeping a familiar playground chant alive in short video form.
