I didn't know that blueberries are also called ball until recently.
Our daughter loves blueberries. She starts saying "more, more" immediately after we handed one to her. Sometimes, at breakfast, she calls for "Ball, ball". At first, I did not know what she was referring to. One day, I suddenly realized that she was pointing to the blueberries on my cereal. They are ball shaped, so they are called balls. My 16-months must be thinking why MaMa does not understand me. Now I really enjoy looking at the world with toddler's eyes.
