Remixes of baby coos and giggles have circulated on short form video apps for years, where creators loop innocent household sounds and set them to a simple rhythm. This bubbling version became popular as a lightweight meme audio because it is instantly recognizable, family friendly, and easy to drop under almost any cute footage. Unlike louder meme sounds like the baby laughing meme, it works as background texture as well as a punchline, which helped it spread across edits, soundboards, and reaction videos.
