Tantrums can be described as throwing a fit when things does not go as expected or when one does not get what he / she desires.
To help a child who throws tantrums, the best way would be to not give in to the child's demands, especially if it is unreasonable and leave the child alone for a period of time for the child to calm down. This should be done at a young age to teach the child that throwing tantrums is not the way to get what they want. If one were to give in to a child's tantrums, this would simply encourage the behaviour.
