Parent-child early education class can let children quickly participate in repeated language interaction with their parents. These cognitions established since childhood have a lifelong influence on children, and the length of time spent with their father will affect children's vocabulary and the speed of language learning. In real face-to-face communication, parents can also understand words by guiding their babies to follow their eyes, for example, pointing to a doll and saying, "Give me the bear". The study also found that the frequency of a word spoken by a mother is closely related to the time when the baby learns the word, and also to the number of words spoken by the mother to the child and the vocabulary of the child.
Early education courses provide a rich social environment to help children learn to share. Like learning other skills, babies need to keep trying and making mistakes when developing social skills. At first, the baby may not want to share his toys with others, but as he learns to care about others, it can help the baby to get through the cognitive period smoothly.
