Essays / Psychology essay- Discuss The Development of Memory in Infancy and Childhood [3]

I have to write this essay on the development of memory in infancy and childhood. I have found plenty of information on the subject im just not sure what there is to "discuss". I think I need to find a few constrasting theories and talk about them but I can't find any theories that clash with each other. If anyone could suggest things that I can discuss that would be great :D
