The 8-month-old baby loves to crawl around, crawling east and west, playing happily. However, some parents are worried about the baby’s tummy crawling against the floor, the tummy is easy to catch cold leading to diarrhea, so they intervene in the baby’s crawling. In fact, it is good that babies learn to crawl. Crawling is beneficial to babies. However, babies crawl on the floor, the floor is relatively cold, if the baby crawls on the floor against the belly, it will indeed make the tummy cold. How to relieve parents’ worries? Will my baby’s belly get cold if he or she loves to crawl? There are differences in body temperature in different parts of the body, but they are limited to the surface temperature, while the internal temperature, especially in the abdominal cavity, is basically the central temperature of the body. Human body temperature is controlled by the hypothalamus of the body temperature center, except for prolonged exposure to cold, the central body temperature will not drop. Exposure of the belly button at room temperature is naturally unlikely to make the central body temperature drop, and is unlikely to change the temperature and peristalsis of the intestinal tube. In other words, parents’ concerns are actually overblown. The temperature of the baby’s belly button is not regulated by the temperature of the belly. From time to time, babies play on the floor, a short period of “intimate” contact with the floor, the belly does not get cold. “Two lift three turn six will sit, seven roll eight crawl week will walk” This is the development process of the baby’s big movements, each baby will go through these stages, crawling for baby growth and development is very important. Intervention in crawling has a big impact on the baby, not only against the natural growth pattern, to combat reduce interest in crawling. Experts remind you: children who do not learn to crawl directly let him learn to walk, may grow up to be hyperactive. Generally speaking, the baby will naturally have the desire to crawl after sitting down and finding a new world in front of him. Crawling can train the baby’s whole body coordination, which is beneficial to his future brain and IQ development, so parents should create a suitable crawling environment for their babies, so that they can fully crawl before walking. “Crawling” is good to expand the baby’s field of vision and range of activities, greatly expanding the scope of information collection and channels, the creation of thinking logic is a huge help; “crawl” and good to promote the development of the baby’s limb coordination movements. The active and active practice of the coordination of the external expression of the baby’s logical thinking plays a very important role in the future composition of the baby’s complete “complex logical thinking”. However, we need to remind parents that it is best to put the baby in the role of conscious and active coordination training when achieving the nurturing purpose of “crawling”. Because a single apparatus or command for the baby to passively complete the “crawl” training process (we call this passive training for small coordination training), will greatly reduce the baby’s interest in “learning” degree.
