Cheerfulness - contented,
in good spirits,
hopeful;
bright, pleasant;
willing, not reluctant.
"It is possible to train your child to be cheerful, pleasant and content, regardless of their natural personality type. Personality differences are very real, yes, but they don't excuse extended moods, contrariness, over reacting and whining.'
(Terrific Toddlers 2, page 73)
