Although my grands don’t live close I do see them regularly and have spent a lot of time with them - either here or at their house. I have always taken my lead from them from when they were small and wanted to cuddle and then read or play with toys or a game to now the two older ones are mostly grown and the youngest who is taller than me still likes to just be with me. We talk or watch a YouTube video - he likes to bake simple things so I have supplies. There have been outings etc but not the main goal. That has worked for us.
