There’s actual science behind why you can’t scroll past a laughing baby — your brain is wired to respond to infant joy before your rational mind gets a vote. That’s why these clips outperform everything else on Facebook: the share happens before the thinking starts.
The prompt below is engineered for that reflex — pure giggling, soft window light, gentle slow motion. Keep clips under ten seconds, start mid-laugh, and always label AI-created babies as AI. The internet’s trust is worth more than one viral post.
