Generate a 10-second video of a baby 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. Ensure the baby is sitting comfortably and supported, but make sure the chair remains in the exact position and angle as in the original reference image.

The camera should stay **fixed in one angle** throughout the video, showing the baby in the chair from a front or side view, without rotating or changing the perspective. Do not alter the product's angle or shape. The focus should be on the product’s structure and how the baby is comfortably sitting in it.

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. Keep the camera still, with minimal movement, just slight zoom-in or subtle focus adjustments to keep the baby and chair in view.
