Baby laughter has long been a staple of online comedy because it is instantly understood across languages and needs no context to feel funny or sweet. Short giggle clips circulate widely in reaction videos, family edits and meme compilations, where a few seconds of innocent laughter can change the mood of a scene without any words. The appeal has stayed steady as short-form video has grown, since creators can drop the sound into a punchline, a cute animal moment or a lighthearted fail and immediately signal warmth, innocence and playfulness to viewers.
