You don't need to comfort your inner child because you had a nice childhood. The inner child concept is usually helpful for people who've been abused and neglected in some way, where their basic emotional and other needs weren't met. If their needs weren't met, they end up being dysfunctional in their adult lives - they learn in therapy how to fill the gap so they're not yearning and needy. I had a good childhood too therefore I don't need to nourish the inner child.
