1.Improve mobility Crawling is a comprehensive fitness activity, which helps the development of the sense of sight and sound, spatial location, balance, and promote the coordination of the body; it can also make the blood circulation smooth and promote the growth and development of muscles and bones. 2, enhance physical fitness Crawling is the first time the baby’s whole body coordination exercise, can exercise the pectoral muscles, back muscles, abdominal muscles and the strength of the limbs muscles; and crawling in the consumption of energy, help babies eat more, sleep well, weight, height grow fast. 3, enhance parent-child communication Crawling can improve communication between mother and child. After the baby can crawl, the success experience under the guidance of parents is increasing, and can get a variety of experiences such as excitement, success and failure in crawling. These experiences can enrich the baby’s emotions, and research shows that babies who crawl often are significantly more excited to see their parents than babies who do not crawl. 4.Promote social development After the infant can crawl, doing things that parents do not allow him to do increases, which objectively increases the opportunity for parent-child emotional interaction; at the same time, the infant can crawl and make parents to require their children with certain norms, and express their displeasure at the infant’s non-normative behavior. These changes further contribute to the infant’s social emotional development. 5, promote brain development Crawling requires close cooperation between the brain and the small brain, more crawling can enrich the neural connection between the brain and the small brain, and promote brain growth. Crawling needs to go through many times of learning and practice; each crawl is the mobilization and stimulation of the brain’s enthusiasm. Therefore, learning to crawl is actually an intensive training of the brain’s nervous system function. 6.Promote language development The frequency of language communication in babies depends on the frequency of body language. Babies who crawl constantly explore the world around them with their own bodies, and many moves have unknown results, so the frequency of parental language is significantly more than that of babies who do not crawl. The parents’ constant verbal cues, body language, and behavioral interactions make the baby understand the accuracy and rationality of language much faster than babies who do not crawl. 7, good character development Crawling brings a lot of unexpected fun to the baby, and “crawling” also exercises the baby’s will and courage, which is conducive to the development of the baby’s personality. Some babies are very timid in the crawling process, afraid to leave the parents are within sight, while some babies are very bold, whether there are no parents around, he can let his own interest crawl to a place they want to explore. 8, the desire to explore the baby’s motor, nervous and other systems in the crawling can get a very full exercise. This not only helps the baby’s bones, muscles, nerves, brain development, but also can lay a good physiological foundation and psychological foundation for them to know the world earlier and better. These learning experiences of babies will be turned into curiosity, so that babies are brave enough to explore, and can develop the ability to solve problems independently and self-confidence in the future.
