One set of my grandchildren have no interest, whilst the other set are fascinated, at times( though not very often now they are a bit older).
It began with photos, of their mum and her brother as children with me, then me and my parents, so they got a sense of being part of a chain through the generations.When they were studying certain topics in primary school eg the Victorians, WWII, I was able to supply some anecdotes which related to my family which they enjoyed.
It has mostly been at my house, or when visiting a National Trust house, talking about things in the kitchen or bathroom reminiscent of my childhood or my grandparents’ house. They are amazed to hear about the bath tub being filled in front of the living room fire for my weekly bath, and the same water being used one by one by my sister then my parents.
But is isn’t something you can force. Like others, I wish I had asked my parents for more information. I am now busy sorting photos and memories into some order, and plan to make it something that will make sense when they are older.
