From what aspects of the baby can we see whether the child's development is healthy?

Hearing screening is needed within one week after the child is born. As long as the screening fails, check again after 42 days. If the re-examination still fails, go to the hospital for a comprehensive examination three months later to see if there is any hearing problem. If there is any problem, choose a regular hospital for treatment. If the child has ear problems, treatment should be started from 6 months. Hearing impairment should be cured before the age of two. If it is delayed all the time, it will affect the development of children's language system. Retinal vessels of premature infants are immature at birth. The younger the gestational age, the lighter the weight, the more prone to pathological changes, unable to distinguish the direction, unable to see clearly, and even retinal detachment. The baby was born underweight 1.5 kg. Retinal examination 4~6 weeks after birth can find problems and solve them in time, so as not to affect vision.

Usually children will call their parents when they are about one year old, and 1.5 to 2 years old will say simple words. If you can't say something simple after you are two years old, you should go to the hospital to check the reasons and then carry out targeted treatment. Children need to be screened for vision at 10~ 12 months. If premature infants or their parents are highly myopic, they need to undergo vision screening for 4 to 6 months in order to find strabismus and amblyopia in time. If the screening fails, it needs to be reviewed every three months. Three years old is the golden age to correct amblyopia and strabismus. Children under one year old need glasses for correction.

Hip dislocation is usually related to heredity. Sometimes, it is not discovered until children learn to crawl or walk. Hip dislocation occurs when one leg has more folds than the other. In addition, if you find that your child is limping, you need to go to the hospital for examination. If the hip joint is not firm, the baby's recovery ability is strong and the child recovers quickly. If it is congenital dislocation of hip joint, it needs to be repaired and fixed with plaster and manipulation before the age of two. If you are over two years old, you must have an operation. O-legs are divided into physiological legs and pathological legs. The former does not need special treatment, and can naturally improve around two years old. Parents can let their children lie flat on the bed and gently put their legs together with their hands to observe whether the knee joint is close to the hip joint. If the distance is not close, and the difference is greater than 15cm, it is called pathological and needs to go to the hospital for comprehensive examination and treatment.

Wrong feeding methods, bad oral habits and heredity will all lead to mandibular inversion of deciduous teeth. In severe cases, the maxilla is underdeveloped and the mandible is excessively prominent. Malocclusion of deciduous teeth is ugly, which will affect the development, pronunciation and chewing ability of facial bones. Children's tooth changing period is the golden period of correction, which usually takes 3~5 months.
