I’d put them oldest further from the hinge. My logic is that they’d be closer to me when I open the door that way (same logic applies whether you store them in the door or fridge). However, of you have a weirdly designed fridge like mine, it makes more sense to keep them on the right side of the body of the fridge because we have double French style doors and it can be sort of cumbersome to try and open the right door and grab the milk if it’s sitting toward the middle away from the hinge due to the left door not being open and my arm bumping it / it being partially in the way. The left side is ruled out completely because there are shelves that are too low and don’t allow enough headroom for the milk.

Did you account for any height difference between you? If she’s shorter then it might still be harder for her to get leverage with the way it’s turned. Just throwing out possible reasons for her convictions idk lol

My partner and I keep anywhere from 3 to 6 half gallons of milk in our fridge at a time. We’re plant based and the stores don’t sell them in full containers. I don’t actually know the milk I bought most recently because they typically all look the same. We try to keep them organized them by FIFO with the oldest in the front so we can grab and use those first without having to read the tiny “best by” dates.

6 is Katy Perry I think?
