“The parents are the authority — full stop on anything involving safety, allergies, or the screen and bedtime limits that actually matter — and I'd state that without hedging, because the hedging is where families get into trouble. Here's the mechanism people underestimate: consistency between homes isn't a preference, it's a developmental need. A young child is actively learning whether rules are real or merely suggestions, and being routinely overruled by a beloved grandparent teaches them, very efficiently, that the rules are negotiable depending on who's in the room. That lesson doesn't stay at Grandma's house; it comes home. So this isn't about controlling the grandparent or winning a power struggle. It's about not handing a four-year-old a live demonstration that authority is whatever they can play one adult against another to get. Hold the line that matters, and hold it the same in both houses.”
