416.8(a) · Children cannot be left without competent supervision at any time. Competent supervision includes awareness of and responsibility for the ongoing activity of each child. It requires that all children be within a caregiver's range of vision except as provided in section 416.8(b) of this Part and that the caregiver be near enough to respond when redirection or intervention strategies are needed. Competent supervision must take into account the child's age, emotional, physical and cognitive development.
