Baby laughter has long been a favourite reaction sound online because it is instantly recognisable and needs no translation, which also explains why it appears under Spanish search terms such as bebe riéndose as well as English ones. Creators reuse it as a baby laughing meme in short-form videos, meme edits and reaction clips to signal innocence, joy or playful surprise, often after a fail or a cute moment. Its appeal has lasted because the emotion is universal, making it a reliable shortcut for lightening a scene without dialogue or explanation.
