There are a number of organisations running Love in a Box operations. In Britain, for example, Mustard Seed sends packages to Moldova and Children in Distress help kids in Romania. Link to Hope’s scheme helps adults as well as children. They made this moving video: https://youtu.be/ii_sr0hu_T0
In France, the American church in Paris is the focus of a network of schools and other associations distributing love-boxes and love-backpacks to children across the country, while in Belgium, the Shoe-box Appeal for adults as well as children collected nearly 50,000 packages last year.
We like the idea of the Backwards Advent Calendar. Instead of getting a small treat on every day of Advent, children put a little something in a box so that by Christmas they have a little stock of goodies to offer.
And, of course, depending on where you live, there are many other ways for kids to get involved in giving and caring, not just for the holidays but all year round.
