Before the age of 2, toddlers seem to be very submissive, but with the pursuit of autonomy, they become less submissive at the age of 2 or 3, often saying “no” and rebelling against parents, which is a phenomenon related to the development of autonomy. Toddlers throw tantrums mainly because their desire to act independently is overly restricted by adults and conflicts with parents’ demands, while toddlers’ verbal expression and control are weak, so they throw tantrums to fight against the restrictions, making parents feel that their children are disobedient and disobedient, which is the so-called “first rebellious period” at age 3. In addition, when young children have to learn to master a skill, the frustration of failure will also cause tantrums. In the baby temper tantrum when reasoning is usually difficult to work, not to meet its unreasonable demands, take distraction, “cold treatment”, “isolation” method is a more effective measure to relieve tantrums, but must pay attention to safety. More importantly, parents should be good at guiding their babies when they are not throwing tantrums, encouraging their children’s independence and ability to develop, and reducing restrictions, so that they can pass through this period smoothly and gradually develop a positive personality; however, if parents do not handle it properly, compromise inappropriately or control too much, the baby’s irrational autonomous demands will develop into capriciousness. Frequent tantrums in children also suggest that there may be problems in the parents or family that require intervention.
