Thank you for your query.
I can understand your concern
Your child seems to have mild ADHD
...which might need behavioural therapy with drug therapy.
cannot be ruled out without performing psychological tests.
The best centre would be NIMHANS or CMC Ranchi.Kindly get an auditory assessment.
If you have any further queries you are free to consult me.Hope this answers your query.Wishing your child a speedy recovery.Have a nice day.
