Chewing gum or chang gam or is it triangle? :)

I am so busy doing some computer stuffs when baby shouted words like chewing gum or chang gam. I tried to look at him hoping I can recognize his words. It is then he pointed at these toy cars. He shouted again and it’s time I recognized that what he is trying to say is triangle with him saying another shape like siko for circle. So, I took a picture of his toy cars and decided to post it here. Gee! Baby is just so funny that he learns to recognize shapes, colors, numbers and letters in less than 3 years old!
