There is no single credited source for this clip, as slowed baby laughs have circulated widely on meme soundboards and short-form video apps as a reusable reaction sound. The slowed effect became popular because it makes an already familiar giggle feel funnier and more exaggerated, fitting edits that need a cute, non-verbal reaction. Creators keep returning to it for wholesome memes, baby and pet compilations, and light reaction videos, where a recognisable laugh works better than dialogue and instantly signals that a moment is meant to be funny or sweet.
