I had bought small little mailboxes from the Target $1 bins. Everyone decorated their own last year with stickers. Then we sat at the table and wrote out valentines to everyone in the family and then placed them in the mailboxes. I had taken the time to print small valentines from a free printable. Just google "valentines free printables" and I'm sure you'll find many cute ones to choose from.

This year we did not need to decorate our mailboxes, but I had put all of last years valentines back in their mailboxes when I stored them for the year. It was fun to go around the table and re-read what everyone wrote to eachother last year before we started on this years cards.
As the mailboxes sat for a few days I noticed the big boys would continue to add more and more notes and small trinkets as gifts. It really was quite a surprise when we finally got to open them Valentines morning. I always make a valentines breakfast and even though it was a school day we still sat down together to eat breakfast. We took turns reading out loud what our valentines said. Sometimes 8 year old boys CAN be sweet.
There really isn't any better way to spend your time together as a family than writing love notes to eachother. So next Valentines take the time together as a family and start your own Valentines tradition.
