cold-treat
Once the baby cries, mom and dad should treat it coldly. Don't coax the baby when he is crying, which will only make him push his luck and not know how to control his emotions.
Pay attention to time (so as to finish or arrive on time)
After the baby cried, mom and dad went up to talk about emotions. Pay attention to the time when the baby cries. If the time is less than last time, it means that the baby has made progress.
Educate babies
Parents can educate their babies with stories they like to watch and stories about their babies around them, so that they can learn to express their needs in a reasonable way, rather than through rebellion.
Let the baby try the feeling of disappointment.
When the baby is two years old, don't satisfy all his wishes. Let the baby try the feeling of disappointment, and let the baby cherish the right to ask more in the future.
Appropriate reward
If the baby behaves well, he should be rewarded appropriately to let the baby know that as long as he behaves well, his parents will be happy.
