Art style: Cinematic Realistic.
Full-length view, the entire figure visible from head to feet, held upright — an eight-month-old baby boy named Kirill, the family's youngest son, supported in a sitting-upright posture as a real infant this age cannot yet stand. Soft round face with plump rosy cheeks, big curious bright hazel eyes, tiny button nose, and a wide gummy smile showing two lower front teeth just emerged. Fine wispy light-brown baby hair, thin and soft on top. Chubby dimpled arms and legs, small bare feet with tiny toes, soft rounded belly. He wears a pale-blue short-sleeved cotton onesie bodysuit with a little embroidered bear on the chest and a soft white bib. Cozy sunlit family living room behind him, warm blanket and plush toys nearby. Delighted, joyful expression, small arms reaching upward.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
