Although some babies may be able to babble at 6-7 months of age, and even some at 7-8 months of age can simply call out to mommy and daddy, these are unconscious and cannot be linked to actual consciousness, so they cannot be considered to be talking in the true sense. By the age of 10-12 months, they are often able to call out simple words and phrases like mommy and daddy very consciously, and at the age of 12-18 months, they are often able to say some short sentences and communicate with adults in a simple way, which means that the child’s speech development is normal and parents need not worry too much. If the child is not able to speak briefly at 18-24 months, that is, at 2 years of age, this means that he or she is too late to speak. It is important to take the child to the child health department or neurology department in time to determine whether there are a series of pathological factors such as developmental delays or cerebral palsy. If these pathological factors are present, interventions such as language rehabilitation should be carried out in a timely manner to avoid serious lag in language development, which may lead to a series of negative consequences, such as a serious impact on communication with others.
