My DS5 fell in love with mazes around 3.5 years old. The thing that confuses me is that he had NO issues whatsoever with mazes but when you have him sit down and try to do one of those "where's waldo" books, he had the hardest time due to some vision tracking issues. He wouid solve a maze in lightning speed and then began to make his own detailed mazes - again, really poor fine motor coordination but when he wanted to make a maze he really focused hard. He also was fascinated with the body mechanics of what happened to food and how it went through your system and anything he could learn about the body - then it moved onto wanting to learn how systems worked - how did the toilet work and where did it go....
