How about getting him a pair of ballet slippers or tickets to a ballet performance? You could also look into a book or DVD about ballet technique, history or famous dancers for him to learn more about his favorite art form. Another option could be a personalized dance bag or a special leotard with his name on it. Lastly, you could consider enrolling him in a ballet class or workshop so he can further develop his skills and passion for ballet.
Or you can get him a star map with the date when he was born.
