A tradition I started two years ago with my kids was “morning mail”. I purchased them each a mailbox (leftover from Valentines Day) and set them up in the kitchen. Each morning (or most mornings) I put something in their mailbox. At first it was some sort of little trinket each day but then it became an occasional trinket but mostly letters, cards, craft items, occasionally a quarter – just something to let them know we thought of them while they were sleeping. They find it very comforting to know that – not that we wouldn’t think of them while they are sleeping but this gives them visual and tactile proof that we do.
Years ago (when I was younger) my father used to leave me a note each morning. His reasoning was different – he worked far away and left the house in the morning before we got up for school. So his lists were more practical with chores etc… But he always wished us a good day. So I remember that important part of each letter.
I hope my children will remember the mailboxes fondly and pass some version of that on to their children when they get older.
