Place it just after the cute reveal in a short edit, then follow it with a cheerful yay to lift the ending, or cut to a cat laugh when the joke turns silly. Keep it as the centre of the sequence and let a goofy ahh sound close the clip.

This clip is a long, unbroken burst of a baby laughing, lasting about 35 seconds, with high, breathy giggles that rise and fall as the laughter keeps going. It feels bright, warm and instantly contagious, the kind of sound that makes a room smile without trying. The laughter stays playful throughout, never turning fussy, so it lands as pure, lighthearted delight.
