Why is daily meditation called a "practice"? Whatever you practice on the cushion for a few minutes is meant to be brought into your daily life. Stillness, presence, mindfulness, calm, breathing, acceptance, forgiveness, loving-kindness or whatever your practice may be, can be brought into daily life.

Have drinking water available to them (to buffer the huge hit of acids that ensue within minutes of candy consumption) and a toothbrush nearby (for the mandatory tooth brushing session within 20 minutes of the candy consumption).
