I have 2 dd who I am using this BIT with. My oldest ,14, is not very consistent with it and so I have seen little progress yet. She does admit that after she does the eye eight exercises her head hurts; tell me something is happening.
My youngest, age 6, is more faithful b/c I supervise her more closely. I think it may be helping. If she is struggling to remember her phonics I usually remember that we have not done the exercises yet and she seems to do better after that.
Dianne Craft is going to be speaking at the CHAP conference in Harrisburg, PA in May and I am planning to hear her speak then. Looking forward to it.
