It's important to get a diagnosis to each person for different reasons, even if it doesn't change anything.
I mentioned on another post that before my diagnosis of autism, which isn't a treatable or curable condition by any stretch, I was labelled alsorts of things: Drama queen, primadonna, crazy, selfish, controlling, bitchy, cagey, etc.
After my diagnosis I was just labelled autistic.
Where people criticised my shortcomings they were able to muster some empathy instead and my self esteem stopped being through the floor because I knew myself better.
My self esteem being through the floor and being told I "just wasn't trying hard enough" was what stopped me seeking a diagnosis in the first place. I can imagine that would stop a lot of people getting a diagnosis if they just felt it was some sort of personal failing that they could beat out of themselves.
My family could research my neurodevelopmental disorder and put strategies in place rather than shout me down for struggling and causing an inconvenience to everyone else.
Externally the only support you're likely to be offered for dyspraxia is OT, and that is hard enough to get for people just recently discharged from hospital or the elderly so I wouldn't bet on that being a realistic option, but if you and your husband understand the disability better, you can both start working on strategies together, but be mindful that what works for some won't work for others, and at the same time, it's important to try and teach your child not to put their fingers in things and accept the possibility that perhaps your child also lacks spacial awareness to a degree larger than his peer group too so you need strategies for both your child and your husband.
