Baby sounds have long been a staple of comedy, cartoons and home videos because they are instantly recognisable and emotionally loaded without any words. Online, very short baby clips are commonly shared as soundboard sounds for reaction videos, edits and live streams, where a single second of noise can change the tone of a scene. Their appeal comes from that contrast: something small and innocent suddenly interrupting something serious, silly or dramatic. That simplicity is why the sound keeps being reused across different formats and audiences.
