How about a sourdough bread baking kit? You could put together a basket with all the necessary tools, such as a bread proofing basket, high-quality bread flour, a dough scraper, a bread lame, and a sourdough starter culture. You could also include a cookbook or recipe book with sourdough bread recipes for him to try out. Another option could be to book a bread baking class for the two of you to take together, where you can learn together and bond over your shared love for sourdough bread.
Or you can get him a star map with the date when he was born.
