Generate a 10-second video of a baby with American features (light skin, blonde hair, blue eyes) sitting in a baby sit-up chair (learning to sit). The baby should be seated with the backrest upright, and the U-shaped cushions should support the baby on both sides. The baby should be comfortably positioned, and the chair’s size should be adjusted to fit the baby’s proportions. The chair should not appear too large in relation to the baby. Ensure the baby is sitting naturally with the chair supporting them correctly. The camera should stay **fixed in one angle**, showing the baby from a front or side view, without rotating or changing the perspective. The product should maintain the exact shape and position as in the reference image, with the camera focused closer on the baby to ensure the chair appears appropriately sized. The scene should be set in a cozy living room or nursery, with soft natural light. A parent can be nearby, offering gentle support but should not interfere with the chair. Use soft lighting to highlight the fabric and details of the chair while keeping the camera still, with minimal movement—just a slight zoom-in or subtle focus adjustments to highlight the baby in the chair.
