"What does inner child mean anyways? I don't feel unloved or desire to be pampered and universally loved. I can give myself more or less what i need... but that does not have anything to do with what I did not get as a child... that part of my life is over, no looking back. And what if that inner child is an annoying brat? Shall we pamper our irrational desires? Doesn't that hold us back in a way if we give in to this concept?"

Your inner child an annoying brat? o0; That would be an indicator to me that it might be difficult for you to be able to "feel one" (for lack of better phrasing) with your inner child. My guess is you were called an annoying brat growing up...or have associations...do you feel you like your younger self? (I don't think that is the most acurate definition of "inner child").
Anyway...I think it has everything to do with not getting what you needed as a child...when abuse happens as a kid-your scared, hurt, confused...and often times the child blames themselves for things like a parents divorce (that's just a start)...so self blame can turn into a dislike of the self/younger self.
