Compliment one precise dish, not just "it's good".
A warm, light atmosphere makes children want to stay at the table. Missions about humour, calm and kind reactions help everyone enjoy the meal more.
Kalmdix announces the mission as a playful quest at the start of the meal, then lets the children talk about whatever they like. It works on one habit over five meals; on the fifth, the mission is a secret. Kalmdix never says who did or didn't do it: the results appear after the meal.
