I have mentioned in the past on another thread a two a book by Jay McGraw (son of Dr Phil). He wrote a book "Life Strategies for Dealing with Bullies". I bought this book for my grandson (10 years old), and read it as well, so that we could discuss it. I highly recommend it. Words are a very powerful tool and it will give your daughter some insight as to how to verbally respond as well as how to handle situations. Couple the info in that book along with the self confidence that can be gained through marshall arts, your DD will be well empowered.
