Does anyone have any experience with it? Think it helped? How did you get your difficult child to do it? Occupational Therapist (OT) recommended Trex do this. She absolultely hates it so it is tough to get her to do the 30 min 2X day. Also, I can't say that we think it helps... she almost seems more easily frustrated but hard to tell as it is also summer and she tends to get bored.
