Whether babies with developmental delay can catch up with their peers depends mainly on the causes of developmental delay, and different causes have different prognoses. The causes of developmental delay can be categorized into two aspects, such as hereditary factors and non-hereditary factors. Hereditary factors: chromosomal, genetic, and mitochondrial abnormalities, such as Down’s syndrome, familial dwarfism, etc. These conditions are difficult to correct and can be improved through early intervention; Non-hereditary factors: prenatal factors such as the mother’s history of medication and nutritional status during pregnancy, and natal factors such as the presence of low birth weight, preterm labor, asphyxia, hypoxia, and postnatal malnutrition, which can be improved by supplementing with micronutrients under the guidance of a doctor, a reasonable diet, and balanced nutrition, and do not require special treatment. If you find that your baby’s development is delayed compared with others of the same age, parents can bring your baby to the Child Health Unit for early detection and diagnosis, identify the cause of the disease, and treat it according to the cause.
