Sandie- I like this article- the 7 tips on harm reduction are helpful- and manageable. Who knew you could get a basic phone ( text, calls). The tip of having no cell/tech zones is good too- like not at the dinner table, sop people can actually talk etc.
Another to consider? when guests come to your house to socialize, everyone put phones in a dish at the front door. Leave them turned on, in case of an emergency.
