Lori, I'm not sure what your question is, but my DS9 was found to have "the core strength of a 4 year old" last summer when he was diagnosed with SPD (with vestibular, proprioceptive and fine motor issues). He always slouched in his chair and layed his head on his desk. He often would lean on me if we were standing together. He has been in physical therapy 2 hours a week and occupational therapy 1 hour a week, plus gymnastics, soccer, baseball and home exercises for almost a year now. His core strength is good now, but it took a very long time and a lot of work to get there. It sounds like your DS is doing all the right stuff, but maybe a couple of months isn't long enough yet to see the result?
