Russian baby talk

So, I've noticed how (the really) young people in russia use weird words while speaking, first I thought they were mispronounciations, but now learned that they are "child-words" or paralell words.

Are there some kind of rule to create these kind of words? :p Could you give some examples of some words with the original words beside them?

I would start with an example if I new any, but I can't come up with one right now. :)

Is anyone actually understanding what I mean?

Yes, I understand. Yes, there is some logic for creating them, although it is applied intuitively.
Should you come up with an example, post it, and we'll try to find an explanation.
