The quality or state of being carefree; freedom from worry, anxiety, or responsibility.
From carefree (care + free, meaning without worry) + -ness (suffix forming abstract nouns). A compound formation following standard English word-building patterns.
Childhood is often defined in literature as a state of carefreeness—but neuroscience now shows that carefreeness isn't natural to humans; children actually worry constantly, so 'carefreeness' is more a cultural ideal than a developmental stage!
