Early development of infants and toddlers is getting more and more attention from the society and parents, especially intellectual development and early education. In this era of very competitive society, no one wants to let their children lose at the starting line. From the law of children’s growth and development, the first few years after birth is a critical period for children’s full growth and comprehensive development in physical, mental, emotional and social aspects, while 0 to 3 years old is the golden period for brain development. Modern research shows that babies 3 days after birth can focus their eyes on their mother’s face, babies half a year old can form initial concepts, babies after 1 year old begin to have reasoning and language skills, and 2 to 3 years old is the best period for developing language. It can be said that 0 to 3 years old is the most sensitive period for the fastest development of motor and language skills. Therefore, parents should create the environmental stimuli needed for the child’s survival and development at each stage of development in accordance with the law of growth and development and its neuropsychological developmental characteristics, so that the child’s physiological, psychological and behavioral interactions can stimulate the child’s overall development and early education can achieve twice the result with half the effort. The effect is twice as great. Each child’s sensitive period does not appear at the same time, so parents should carefully observe the emergence of sensitive periods. When a child’s sensitive period is observed, parents should try to prepare an environment that meets the child’s growth needs and encourage the child to explore freely and try bravely. I, the key period of movement development Movement and movement development can promote physical development, expand the range of activities, development of observation, increase interaction with people, help to develop the child’s ability to live independently and lively, brave, perseverance and other good qualities. 0 to 3 years old is the baby’s motor development sensitive period, the baby was born from the supine position to be able to walk and run, from reaching for things to be able to use both hands flexibly are completed before the age of 3, baby The sensitive period of raising the head is 2~3 months, the sensitive period of sitting is 6~7 months, the sensitive period of walking is about 1 year old. 1 year old after the movement development is more rapid, the coordination ability of hands and feet is further strengthened. The sensitive period for hand movement development, such as reaching for objects, is about 5 months, and the sensitive period for fine hand movements is 1.5-3 years old. According to its characteristics, it is appropriate to focus on the cultivation of coarse movements and the fine movements of the hand and fingers. Specifically, the following aspects can be carried out: 2 months after birth can be trained to lift the head, prone, chest movements. 3 months, to help children from supine to side lying, to complete the rollover action, training the ability to actively change position, posture, in preparation for crawling. 5 months to help children learn to sit, but not too long, to avoid spinal bending, 4 to 5 months, to train their grasp of the chest toys; 6 to 10 months You can train your fingers to take small objects and create a crawlable environment. After 1.5 years old, on the basis of walking steadily, train children to walk up and down stairs, run, jump and climb, practice alternating feet to stand alone, so that the strength of both limbs is balanced, teach children to jump, and let them practice jumping down from steps and jumping long distances to promote the development of large muscles. The child can also practice jumping down from the steps and jumping long distances to promote the development of large muscles. Take children outdoors, to the park and to the grass for games and running to promote the development of their mobility. Children can learn to draw, build blocks, string toys with holes on plastic ropes, learn to use chopsticks to fetch things, and fold paper to train the flexibility and accuracy of fine hand movements; they can also promote the development of hand stability and coordination through games, crafts, and doing what they can. The critical period of language development Language development promotes human interaction and is the basis for children’s learning, and is a major component of intellectual development. A baby’s language sensitivity period begins when he or she begins to look at the mouth of an adult and make yapping sounds. Language ability is divided into oral language and written language ability, before 3 years old is the sensitive period of oral language, 0-1 years old is the pre-language period, the child from like to hear can understand; 1-3 years old is the language period, which 1-2 years old children can use only words to express their own meaning; 2 years old after the child After the age of 2, the child enters a period of language explosion. Parents should provide their children with an appropriate environment for speech and language perception, so that infants can fully perceive language and communicate with them frequently. At 2 to 3 months of age, the mother can use breastfeeding to “talk” with her baby. When the infant begins to learn to speak, she should take the initiative to teach him/her the correct pronunciation so that he/she can actively imitate the language of adults. Through daily contact with people and objects, the infant is guided to relate objects, things, and actions to expression. Suitable language stimuli for infants include radio broadcasts, short stories, children’s songs, and affectionate verbal exchanges, all of which can arouse an infant’s interest in perceiving language. Children begin the language comprehension stage with high verbal motivation later in life. As they grow older, life becomes progressively richer and opportunities for verbal communication increase. It is important to develop and deepen their understanding of language and their ability to express themselves, to use different occasions to create opportunities for verbal communication, to teach everyday language, to inspire children to speak; to teach children to recognize people and things around them, and to exercise their language skills. To speak Mandarin with children more often, pronunciation should be correct, diction should be clear, and statements should be coherent and complete. Encourage children to express their requirements in language, and correct mispronunciation when imitating adult language, so that they can spit out words clearly, use correct words, pronounce words accurately, and make statements coherent and complete. The child’s language vocabulary should be constantly enriched from simple to complex, from monophonic to polysyllabic words. With the development of language comprehension, children can be further taught to read short sentences and children’s songs; retell some simple fairy tales, and make corresponding actions according to the requirements. Third, the key period of behavior habits as the saying goes: “three years old, seven years old”, “the mountains are easy to change, nature is difficult to change”, indicating that once a person’s character is formed, it will become a more stable personality traits, which will have a great impact on the child’s future life. 0~3 years old is a critical period for the formation of children’s character, a sensitive period for children’s imitation ability, and the first period of rebelliousness. Therefore, it is necessary to provide the right amount of conditions at the beginning of the formation of the child’s nature, to establish good behavior habits. First of all, parents are the first teachers of their children, and they have to play an exemplary role. Cultivate good sleeping, eating, hygiene and other habits and love of work and care for others; train the ability to take on and off clothes, shoes and socks, unbutton and shoelace, etc. to take care of their own lives. Encourage children to build confidence in overcoming difficulties, and when they encounter difficulties, teach them not to reach out immediately to help, but to encourage them to try, as the success of children’s attempts will greatly contribute to the development of future intelligence and the development of the will to learn. Teach children social knowledge, moral codes, behavioral norms and social skills in many ways, and provide them with places to practice social behaviors and skills. Let children do role-playing games together, so that they know how to abide by certain rules, cooperate with each other, unite and love each other, and build relationships with their peers through such games. Bring children into contact with society more often and teach them to address people around them politely. Cultivate children’s good moral qualities and emotions, such as teaching children to love toys, be polite, not to throw fruit skin, take the initiative to clean up toys, not to pick flowers in the park, not to urinate and defecate anywhere, etc. Adults should respect children, do not comment on their shortcomings to their faces, and if they make mistakes, teach them to recognize their mistakes and be brave enough to correct them, and praise and encourage them in time after they have made efforts. Children should be praised for their good behavior and criticized and corrected for their bad behavior in time.
