Hi. I understand your concern. Risnia is not a solution for lack of speech. Does your nephew also have behavioural issues like anger or temper tantrums?

Hello. The prescription you have attached is by a psychiatrist for mental health disorder. To be able to diagnose your child, there is need to examine him, take family medical history and review his other developmental milestones as well. Than after a proper diagnosis treatment can be started. It must be very concerning for you that child only speaks gibberish but for the doctor evaluating the case, it may be a symptom of some other pathology. So you can get review case with me with all details via practo.
