There is no relationship between early and late walking and intelligence, so a baby who walks late may or may not be smart. Generally, babies learn to walk between 10 months and one week, and the early and late walking is related to muscle development, bone development, and the child’s personality. If the baby is late in walking, parents must pay attention to the possibility of progressive bone dysplasia, calcium deficiency, malnutrition, or congenital genetic diseases, if the baby can not walk by 15 months, it is best to go to the hospital for examination.
