The critical period for a child to learn to speak is between the ages of 1-3 years old, while the language explosion period is around 2-3 years old. Every child learns to speak at a different time. Under normal circumstances, babbling begins at 7-8 months of age, at around 1 year of age, children can call out single simple words such as dad, mom, etc., and around 2-3 years of age is the language explosion period. During the language outburst period, the child’s language will explode like a blowout, and it is important to seize this period for the child to learn to speak. Children learn to speak mainly through imitation. Parents can talk to their children more often, and when talking, they should look at their children’s eyes so that they can clearly see their parents’ faces and mouths, which can be accompanied by facial expressions and gestures to make them interested, so that it will be easier for them to learn to speak. In the child’s language outburst period, the speech is usually not organized, parents should have patience, listen carefully, and give more encouragement to enhance the child’s self-confidence.
