I shop online, but before that I use to bring my kids all 5 of them shopping, as did every other parent, some even brought the grandparents too. I needed dhs help as we needed 2 trollies, so yep, we looked like a crazy fuckin family going around.
The thing was though, it was actually OK, the kids hung off the back of trollies, they would sit in the trollies, I use to give them 3 things to go get, they all legged it off and came back with the stuff, OK so there wasn't as much variety in the dark ages but damn it was good for their memories and reading skills.
I could never be sure if one would go into a sulk and start moaning, but that's kids for you, the best mannered can show you up at any time.
I am thankful they are grown now and I don't need to bring them with me because I hate supermarkets now and I despise the smart arse comments from the checkout operators about how much I'm buying, supermarkets were never like that, so I still shop online, although I get it from the delivery drivers but I can stick my two fingers up at them while they're out getting the million crates from my family of 7.
I say if you want to bring every member of your family shopping go for it. Who actually cares really.
