 Parents have moral and legal rights regarding their children. They have the liberty to make decisions on behalf of their children regarding matters such as diet, schooling, association with others, and—more controversially—religious observance, and the right to exclude others from such decision-making. Such rights decrease in strength and scope as children gain decision-making capacity, yet until the child reaches moral or legal competence, issues of substituted judgment and surrogate decision-making remain (Ross 2002).
