my DS's diagnosis of DCD (developmental coordination disorder)came about after it was noticed by nursery staff that he shakes concentrating on tasks that require hand eye coordination, and they told me to take him to our GP, who in turn referred him to paediatric consultant. Now he is diagnosed, we are waiting to hear from OT. he is 4 and 2 months.
DS is super tall too, and bright, and i thought he was just a bit giddy, like me... a bit...dyspraxic! i was ur-diagnosed in my early 20's, my dad also has it... so in answer to one of your questions, yes, it is something you just have to learn to live with- my dad is very very successful in his field if a little 'maverick', and the same could be said for me. because i had to work harder at some things than other children, i became a bit obsessive over them, and i can see my son developing the same eye for aesthetic detail. i think i can speak for my father, though, when i say we would both have appreciated knowing what it was that was different when we were children.
the main concern over DS by all professionals involved is that at present he is an happy, confident and articulate lad, when he gets muddled up he just laughs it off-i encourage this- and the fear is that various knocks to his confidence by his differences in ability are going to affect his self esteem, and therefore his sociability. he already backs away from things he doesn't feel he can do like drawing or writing, so i am spending lots of one on one time encouraging him to make marks, with limited success at the moment, but it's early days. one thing i can get him excited about is 'catch'- even if he (and me, if i'm honest)can't actually 'catch' the ball half the time!
i'm sure the OT will make a big difference, but mainly i'm happy about the diagnosis (after getting over the slight shock that my child isn't entirely perfect, but who is, and wouldn't it be boring if they were) because, hopefully, it will ensure he'll betreated with a bit more tolerance and patience than i was as a child. i hope it does not mean that anyone writes him off, or that he doesn't learn to apply himself to things he finds hard.
in short, talk to your GP or HV. my GP was pretty dismissive at first, asking lots of vague questions about 'well, what is normal', and it was really conviction of the nursery staff that something was really up ( i'm probably normalised to coordination problems by having them myself) that drove the referral. i think its up to you, depending upon what you perceive extent of his difficulties to be, whether or not you think the diagnosis and the outside support will be helpful, or that putting a label on this is going to be more of a hindrance to his learning to cope with this effectively. i can see both sides of the argument.
