My grand daughter, 2 years old, speaks very little.She speaks only one word at a time like dada, mom, i, etc.She is very intelligent as such and does understand everything we tell her.She can also make us understand what she wants by her actions.Inspite of our lots of efforts, she does not speak more than one word at a time.He father also started talking when he was two years old. He speaks alright after age of 2 years.His older daughter has no problems of speech. Could you tell me if this can be cured?What are the remedies?How much time it could take to be alright after the tretment?
