I make a point of getting all my grandchildren together as often as possible so their earliest and fondest memories will include each other. Our favorite ritual is a huge pile-on so we can read and re-read a book I created for them, which is full of photos of many of their adventures together. The kids are all wearing their tie-dyed clothes, which are the result of another treasured ritual- a two-week summer "Nonna Camp" that I host for them every year.
