In the coming years I think that Piaget's principle of stages and debate that surrounds around it is what will stick with me the most. Growing up my parents talked about the stages of development and that my cousins were "just in that stage." Through learning about the controversy with Piaget's principle I have learned that development is much more continuous than when I grew up. This is obviously important to know as my friends and siblings are having children of their own. This controversy is something that will affect many, even without having children of their own.
It's amazing that the idea of babies developing "in their own time" is not a new concept. I know especially with some of my friends that have children that they start to worry when their children aren't where they should be in development. With the concept of development being continuous, using this information will greatly ease the worries of those in my life that some may call "Nervous Nellies".
