Doing something is a healthier way to fight boredom than eating something. Try entertaining him with books, toys, crayons or colouring books to prevent a tantrum. When you hand out snacks to calm your restless child and prevent a tantrum, you teach him that food is a fair substitute for mental or physical stimulation. This association can stay with him for life. Instead, think of snacks as mini-meals, not treats. Serve them at regular times of the day (such as just after naptime) and get your toddler to sit at a table when he eats. Offer snacks that provide a healthy balance of protein, fat and carbohydrates. Try wholewheat crackers and low-fat cheese, apple slices or carrot sticks and hummus.
