For instance, gently turn the puzzle piece so he can put it in by himself. When you sense your tot is reaching the brink, create a diversion towards a calming, soothing activity - a different place, a toy, a hug, a story, a song or perhaps a snack. Keeping a tantrum diary might help you understand triggers. Try to think ahead and limit overwhelming situations. For instance, plan short shopping trips when he isn't tired, take nutritious snacks whenever you go out and don't wait for difficult behaviour before you offer food.
Some foods can adversely affect children's behaviour.
Again a tantrum diary might shed light on tantrum triggers. Encourage toddlers to express frustration or anger verbally. If their language skills are limited, help out. And please, don't walk away from an out of control tot in places like shopping centres. It is scary enough to be out of control without also feeling abandoned.
