Bloom foundations

Well I finally got my descartes Baby book.  In the first chapter Bloom discusses that when a infant is shown a item on the floor and then it is covered up.  The child believes that the item has disappeared and is surprised when it is uncovered.  Could this be why playing peek aboo is so entertaining to infants, but if I was to do it class everyone would think I on drugs?  The thing is now my duaghter will grab a blanket or hide behind a door ( not all of her just her head) and play peek aboo with herself, and still laughs and acts surprised when the world is uncovered to her.  Sometimes I wonder if she is just trying to figure out how it works.  After reading this chapter I started to wonder how much money toy companies have put into figuring out what will hold a babies attention the longest.  Looking around my living room while I read this made me start to think, So thats why they have the lights do that, or sounds or levers.  anyhow just random thoughts for the day.
