Compatibility/Family
Parents and children do not choose each other's temperament. Things tend to go best when what a parent expects fits who the child really is, an idea called goodness of fit (Thomas and Chess, 1977). For a young child, pick the type you see most often and hold it lightly, since personality is still taking shape.

Shown separately, not part of the fit
Developmental research has long held that children do best when what their parents expect fits their temperament (Thomas and Chess, 1977). A meta-analysis found that parents who are emotionally steadier, more agreeable and more conscientious tend to show more warmth and structure, though the effects are modest (Prinzie et al., 2009). Personality keeps developing well into adulthood (Roberts et al., 2006), so treat a child's type as a working guess.
Every setting reads the same five scores through the areas that matter there.
