There are so many little triggers that take me back to childhood memories with Grandma and Grandpa! Some are smells. Some are sights. Some are songs. I have some of them captured on my Shared Memories page. Grandparents.com also has their article What Grandkids Remember that I shared a while back on starting new family traditions.
Foundations from the Past by Jean Warren has more great ideas as well to teach the children about their past and their family history. Check it out!
