Each baby’s development will be different, we generally do not advocate comparing with other children, but if the baby’s motor development status is significantly later than the same age, it should be noted that this may be a motor development delay. Which babies are prone to motor delays? How can we tell if the baby is motor delayed? 1, the baby big movement development time: turn over time The baby is about 4-6 months after birth began to learn to turn over, the baby will turn over the peak period is in 5 months. Babies can lift their legs and twist with enough strength, it is easy to roll over. Rolling over is the baby’s first means of mobility. The exact time when a baby will turn over at several months varies from person to person, so mothers can not be anxious about their baby turning over late. Because there are many factors that determine the condition of the baby turning over sooner or later. Baby development condition time standard 2, baby big action development time: sitting and standing time Usually, most babies will learn to sit alone when they are 7~8 months old. At the beginning, the baby’s body leans forward and uses both hands to help support the body, and sits for a while before falling over. Slowly, the baby’s balance develops and he or she is able to sit up straight without the support of his or her hands. By 8 months, the baby is sitting better and better, and even able to lean forward to grab toys. 3, baby big action development time: crawling time 7 to 9 months is a critical period for babies to learn to crawl, parents should try to seize this time to teach babies to learn to crawl. In the process of learning to crawl, the baby’s will is particularly important. When babies first start to learn to crawl, there are various ways to move around. For example, some babies crawl backwards; some babies spin in place; some babies rub their bottoms and move; and some babies have their abdomens on the ground and creep forward, unable to support their bodies with their hands and feet. These are the process of baby crawling. When babies really crawl, they crawl on their hands and knees, their chests and abdomens leave the ground, and their heads and necks are raised. 4, baby big action development time: standing time General baby in about 8 months old can be supported by slowly learn to stand, 9 months old can climb holding furniture to stand up, to 10 ~ 12 months old will be able to stand independently. When babies first learn to stand, usually with the help of reaching to the support of the furniture to stand up, slowly, you can use your hands and feet to stand up, until the foot strength gradually developed, can use the entire foot to support the weight, the baby will be able to stand stable. 5, baby big action development time: walking time Baby grasping the mother’s two fingers, can move forward, and then, their own 1, 2 steps, most babies will walk time, is between 10 ~ 16 months. When babies first learn to walk, they need to barely hold up their hands to keep their balance, slowly alternating between their feet and wobbling forward. As babies gradually master the skills of walking, they will be able to hang down their hands to move forward. Generally by the time the baby is about 2 weeks old, he or she will be able to walk quickly as well as trot. After the baby learns to walk, he will be able to freely go where he wants to go, the baby’s vision has expanded, which is a very important milestone in the baby’s growth.
