Setting limits on the behavior beforehand can also help minimize tantrums because the child will know the consequences of his or her actions. For example, if a child frequently throws a tantrum in a particular environment, tell the child before going into the situation what type of behavior will not be tolerated. If children want something and think they might possibly get it, they will persist with their crying and screaming until they get what they want. Also, remain consistent and don't give in to a child's demands after previously saying no. Inconsistent behavior will send the message that the child can get what he or she wants by throwing a tantrum.
Parents have to decide what the child does and make decisions by saying yes or no.
And they have to follow through with what they say. If the child feels that the parent is in control, the tantrum is likely to be shorter. Trying to reason with a child during a tantrum will not work. And spanking becomes abusive if the child has frequent tantrums. Or as a last resort, they can simply take the child and leave the scene of the tantrum.
