It is so hard for me to explain motor dyspraxia and hypotonia and "glitch" days to other people. I don't understand how those neural connections are working one day and not another.
Yes, we are dealing with the same disabilities (plus a couple more) you'll never get everyone to understand it. More important to help your son find ways to maximize the abilities he does have and to learn to use his gifts to compensate. Also, he's getting old enough that he might be able to start spotting patterns of what causes the bad days or what kinds of activities tend to help him feel more organized or back on track - for example for some kids with sensory problems on "bad days" they can get back on track with deep, calming joint-muscle input.
Lots of practice does two things. First, it will increase strength which can help compensate for low tone. Second, it should help with the motor planning part of it because the more he practices the stronger the neural pathways will be and the less effort it will take from him.
