My parents aren't old enough yet that they'd need my help with that. Well, not entirely. My mom had asked me for advice in the past when my dad was on business trips and things couldn't wait until he returned. It was rare, but not unheard of. But I remember my mom and my aunt (her sister) doing that for their parents and having their typical loud-voice conversations in our kitchen about such things, and also my dad doing it for his parents. Not just exploitative stuff, but also things like dealing with companies (like a plumber) and administration, and later on when my grandparents got sicklier they also did most errants/shopping for/with them, took them to the doctor and so on. My dad even ended up taking legal guardianship for my grandpa, as my grandma was considered "unfit" by the court. And later, he did the same for grandma, when she deteriorated further and it was a choice of her being under his guardianship in her own home with professional help once a day and him doing the shopping and keeping the house clean etc, or the state taking guardianship and putting her into a retirement home against her will. He went there straight from work each day for an hour or two until she passed. I'd say it's more common than not.
