Freud in AP Psych

I first learned about Freud in high in AP Psychology. I do not remember Freud being a touchy issue but now I can see how some could take an offense to it. I remember one particular thing Freud believed: oral fixation. Therefore, an infantile oral fixation would be manifest as an obsession with oral stimulation; yet, if weaned either too early or too late, the infant might fail in resolving the emotional conflicts of the oral, first stage of psychosexual development and he or she might develop a maladaptive oral fixation.As a sixteen year old, I believed this concept was very funny, and I still do. Whenever people suck their thumbs, chew on the string of their sweatshirt, chew gum continuously, and bit their pens/pencils frantically, I think of Freud and wonder if these people developed these habits as very young infants. If oral fixation is true, mothers really need to pay attention to the amount of time they do or do not breast feed. It is interesting how Freud took a very simple concept, such as breast feeding, and made it into a cause of things like oral fixation.
