Parents in some aspects of childcare to pay special attention to some behaviors for babies should not be done too early, at the right age to do the most important behavior for the physical development of babies, the following 6 things parents must know! A, learn to walk normal time: about 1 year old premature hazards: 1, affect the child’s physical development: infant bones in the gelatin, calcium less, soft bones, lower limb muscles and keep the arch of the small muscle group development is not complete, too early for the baby to learn to walk, the weight of the body will certainly increase the burden on the spine and lower limbs, over time, easy to make the spine and lower limbs deformation. Fat children should not learn to walk too early. 2, affect the child to learn to crawl: crawling practice has very many benefits for the development of children, but crawling than walking hard, and vision is not as high as walking to see far, if the child learns to walk too early, the child will not want to crawl and choose to walk, so the baby missed the golden period of crawling practice. 3, affect the child’s vision development: because the baby’s vision development after birth is not yet sound, can only see clearly near objects, prematurely learn to walk, the child can not see distant objects, the need to adjust the diopter and focal length of the eyes to focus on the scene, which will produce a fatigue damage to the child’s delicate eyes, repeatedly can damage vision. Second, riding a bicycle Normal time: 5 to 6 years old, the start of premature harm: young children’s bones are in the developmental stage, plasticity, and muscle strength is very weak, riding children’s cars, the lower limbs to spend a lot of effort. If the legs are in a state of muscle tension for a long time, but also let the bones of the lower limbs for a long time under stress, very detrimental to the growth and development of the bones. Children’s tricycles currently on the market, the distance between the two pedals becomes wider, and the distance between the seat and the pedals is too long, some cars can not adjust this distance. Thus, when the child rides up, the feet and lower limbs very hard, over time the formation of the two knees protruding inside the expansion, the two lower limbs excessively outward, the formation of “X”-shaped legs, and even some children formed inside the eight feet. Third, learn roller skating (single row) Normal time: 7 years old before learning single-row skating Early hazards: 1, the legs easily lead to deformation: because single-row skating requires the legs to the outside skimming, under 7 years old children’s bones are not yet mature, easy to lead to X-shaped legs; 7 years old before you can learn double-row skating. 2, easy to be injured: play roller skating waist, knees, ankles need to force to support the body, once the force is not appropriate, these parts are very easy to be injured. Therefore, in general, children under 12 years of age to play roller skating, to have professional guidance, and is not suitable for a long time to play roller skating. Fourth, drawing circles Normal time: 1.5 years old after the start of continuous circle drawing, two and a half years old before the circle closed. The dangers of premature: children drawing circles is actually a kind of doodling, which is the spontaneous behavior of children. Do not teach your child to draw circles and other shapes in advance, otherwise it is likely to hinder your child’s enthusiasm for creativity as well as bind your child’s imagination. V. Dividing left and right Normal time: school age 5-7 years old can establish self-centered left and right, around 7 years old can distinguish the left and right of the person standing opposite him; 7 to 9 years old. Children can distinguish left and right spatial relationship to intuitive and visual things, and form intuitive representations 9 to 12 years old, children can form abstract concepts of left and right orientation, and can establish their spatial relationships based on representations and memories. Warm reminder: the harm is not to talk about, but there is the disadvantage of wasting time. Too early to teach children to distinguish between left and right, children can only mechanical memory, if not insist on reinforcement, after a while will forget. Normal time to learn drawing skills: after 8-9 years old The dangers of premature learning: children enter the stage of “visual realism” when they are about 9 years old, and their perspective of observing things is close to that of adults, so it is more appropriate to learn drawing skills at this time. Sensory realism” stage, when the child draws what is in his or her mind. Children draw to express their thoughts and tell their feelings and discoveries through painting. If children are taught adult drawing skills too early, it may hinder their enthusiasm for creativity and is not conducive to the development of imagination.
