I love finding healthy and yummy treats that my kids love. One of their favourites at the moment is so simple. They call them grape sticks. Basically you thread grapes onto a bamboo skewer (or paddle pop stick for younger kids - no pointy end). Then stick into a snap lock bag or container and freeze. In summer they eat them at almost any meal breakfast/ morning tea/ after school snack/ dessert.
As sweet as an ice block but a much healthier option!
