Listen to some stories of romance
At Storynory you can download stories for free
Watch a romantic film.- obviously your choice will depend on the age of your kids , how about;
Cinderella - maybe a modern day version like Maid in Manhattan or Pretty Woman
Roman Holiday or another Audrey Hepburn film.
The Time Travellers Wife
The Princess Bride
.....the list is endless! A Disney list here
Make an appreciation tree. Cut out paper hearts, each heart should have the name of one family member on it, distribute them to family members who then write something they appreciate about every person on the heart with that person's name. Hang the hearts on a branch and place in a jug on the table.
I am going to give my family a quest this year - the one that can find the best definition of true love will win a chocolate heart.
Any other ideas?
