Thanks TCF. I do hand feed her up close myself several times a week in addition to her group lesson. I just don't have any experience coaching a Junior player thus my posting on this forum. I am trying real hard to get her fundamentals correct, so I will try those tips you mentioned.
Thing is the club where she is taking her group lessons is considered prestigious around here with several top juniors training there. Her coach last week told me she was ready for the next level which uses the green dot ball. I took his world for it, but I knew there was something not right about her technique. Thanks again for point out the flaws.
