AI Video Prompt: Baby & Dog Grape Moment

A realistic vertical smartphone video inside a public transport vehicle. A cute baby with a small top ponytail, wearing a yellow sleeveless outfit with a star design and a small blue cross-body bag, sits on a blue passenger seat beside a small white fluffy dog. An adult standing nearby holds a bunch of purple grapes close to the baby. The baby notices the grapes with a curious expression, slowly reaches toward them with a small hand, and interacts naturally while the calm white dog remains seated beside the baby. Keep the exact vehicle interior, blue seat, characters, clothing, dog appearance, grapes, lighting and camera position consistent throughout the entire continuous shot. Use realistic smartphone footage quality with natural autofocus, slight handheld movement, authentic indoor lighting, realistic baby expressions, natural pet behavior and accurate physical interaction. No cuts, no extra characters, no background changes, no artificial effects.
