yes, when DS8 was 4 he did sudoku also. And reallllly complexy mazes lol People would look at his maze book and raise an eyebrow lol I didn't think it was too out there until he got older and i looked back at it all. Let's see, what else... he got really interested in Weather. He is always on the radars and weather websites, loves books about weather.Currently he is into making stop motion movies.
