Question
My child is over two years old, and now they can only say simple things like ‘Dad’ and ‘Mom’. They have difficulty concentrating, know what they want by pointing without speaking, and don’t listen to adults. I’m worried they might have pediatric intellectual disability. What are the manifestations of pediatric intellectual disability?
Answer
The manifestations of pediatric intellectual disability include: at one month old, the eyes cannot follow a moving red ball or a person walking; at three months old, there is no response to sound; at four months old, cannot recognize family members; at six months old, there is no response to their own name; at seven months old, cannot recognize strangers, does not produce sounds like ‘da-da ma-ma’, and cannot actively grasp objects with their hands; at nine months old, cannot imitate sounds, does not express welcome or goodbye, and cannot use their hands to pick up small balls; at ten months old, does not have hand gestures or eye contact for common objects and people; at one year old, does not know how to cooperate in dressing and does not consciously call ‘Dad’ or ‘Mom’.
