Shopping lists: any tips?

[notaflyingmonkey]

Mum has dementia. I visit a couple of times a week and take her shopping each time. The problem is when I phone to ask what she needs, it's always the same things which are usually not needed at all, but she thinks they are (eg tissues, which she has mountains of), but overlooks the things that she does actually need. I've tried starting a list, but it just disappears. I've tried saying look in the fridge, but that doesn't do it either.

Any thoughts on how I can make it work better?

Could you make a master list and print lots of copies? Could you check supplies with her on one visit? Then shop before next?
Not easy!

I think the problem is that even though I know she has dementia, and that affects her ability to process these things, I sometimes unconciously play along with the pretence that it isn't so. And there is little point in me pointing out the stockpile of tissues. I think you are right sandwich I need to own it myself.

I do a weekly online shop for my parents. We have a core standard list. Works fairly well.
