Grandson has worked out that at our house the tablet rule is "ask Dadu"
He's 8 and stays with us two afternoons a week. His parents allow half an hour of tablet on school days. With us he asks politely, I say yes, and somehow it's an hour. I don't want to be the soft one who undoes their rule, or the strict one he stops looking forward to. How do other grandparents keep the same arrangement as the parents?
