The dominant feeling

What is the dominant feeling of childhood? or what was the dominant feeling of your childhood? Did some emotion occur more than others? Or was there some emotion that occured perhaps rarely, but now occurs much less or ever never?

I don't want to romanticize childhood, but I'm guessing that the feeling of wonder often dominates childhood. That feeling when you look at something, and it mystefies you, and you are somehow curious about it, and as if there is an explanation (not something technical) and knowing it matters or would be better.
