I have a daughter who is 9 yes old studying in 4 th standard. She is quite hypersensitive. However I am finding that she is witnessing concentration lapse in her daily studies. For example inspite of knowing arithmetic methods of addition, subtraction, multiplication or division she commits silly mistakes. Similarly while writing answer in English or hindi there are lot of spelling mistake. She hardly devotes more than 10 minutes in one stretch. Kindly suggest me either in form of medication or otherwise how to improve her concentration.
