Create a finished, home-printable Santa letter on a vertical 3:4 sheet, with generous safe margins and a warm, tender feeling for a baby's first Christmas. Use soft pastel blue stationery with a subtle, lightly textured paper surface, a fine blue border, and just a few delicate golden stars. At the top, set the small letterhead exactly as: “NORTH POLE”. Below it, arrange this exact letter copy in a clear, friendly, large serif that a young child can read; keep the wording and punctuation exact, with no additions, omissions, or other text: “Dear little Theo, welcome to the world! I can't wait to visit you on your very first Christmas.” Give “Dear little Theo” gentle visual emphasis while keeping it part of the sentence. Set the closing beneath the message, with an elegant handwritten signature feel, exactly: “Love, Santa.” Make the body the main focus, spacious and easy to read; do not shrink or crowd the text. Add one tiny, sweet teddy bear illustration near the lower right, softly rendered in warm cream and pale blue, with a small blue ribbon. Scatter only a few small stars around the open areas, never over the writing. The overall design should feel like keepsake North Pole stationery: calm, magical, tender, polished, and uncluttered. Use soft blue ink, restrained warm gold accents, and subtle paper shadows. No other words, names, motifs, characters, or decorative clutter.
