The Young Carers' Initiative is an organization here in Canada supporting kids looking after their parents or grandparents. In the UK, Young Carers has this role. In the United States, The American Association of Caregiving Youth does terrific work to support young people who take care of a relative needing help to get through the day.
Whether or not young people should be asked to care for their relatives who are infirm because of age or disability is an ethical and economic question. I believe the answer to the ethical question of whether our young people should have caring responsibilities is a relative one. Relentless cutbacks to social care budgets leave some family members giving care in positions of powerlessness and isolation. The downloading of ever more complex nursing duties to family means that some caregivers, including those under 18, are coerced into giving levels of care that make pursuing other interests (such as school) impossible. Giving some care on a regular basis can be a powerful ingredient in developing responsible maturity, but like any good thing, too much can be toxic and life-limiting.
Bravo to these organizations supporting young carers and helping them achieve balance in their lives.
