Supervision needs vary significantly based on the child's age and developmental stage: - Infants (0-1 year): Require constant supervision due to their vulnerability and limited mobility. - Toddlers (1-3 years): Need close supervision as they explore their environment and develop motor skills. - Preschoolers (3-5 years): Benefit from slightly more independence but still require adults to guide and protect them. - School-aged children (6-12 years): Can handle more autonomy but still need supervision, especially in unfamiliar or risky situations. - Adolescents (13-18 years): Require less direct supervision but need guidance and support to make safe choices.
