The fuller answer
Grandparents may raise a child because of death, incarceration, addiction, illness, military service, family conflict, or another crisis. The home can be deeply loving while also containing grief, aging worries, money pressure, and generational differences.
A young person may feel grateful and angry at the same time, worry that a grandparent will die, or feel embarrassed explaining the arrangement. These feelings do not cancel love.
Grandparents may need help with school systems, technology, transportation, legal authority, health care, or benefits. Asking for outside support strengthens the family; it does not prove failure.
