Sorry - I realised this was really for adults, having DS1 diagnosed makes it very clear DP is also dyspraxic (they are peas in a pod in so many ways).
We do the same for him! He travels a lot for work, so he has a fixed kind of packing list, even packing for the gym, he comes in and goes through the list he has to make sure he has everything (water bottle, sweat towel, clean pants etc.). He never undoes his shoelaces, rarely unbuttons his jeans - he just drags them on, and we just buy a variety of whatever he needs until he finds the one true waterbottle/gym bag/whatever that works for him (and then he buys 5 of that one thing so he doesn't have to do it again for a while).
Driving - he generally takes a taxi (public transport is a mystery to him - I've had to rescue him from various places when he's managed to get on the wrong train/tube/tram - the maps baffle him and he goes in the wrong direction) or I drive - although he did pass his test eventually - he just finds it tiring.
Day to day, it's just just DS1 - routines where we can (he's an adult, so not as trainable!).
For work, he's lucked out a bit. Finding writing and organisation hard has made him extra diligent - which it turns out is very useful when it comes to doing budgets - plus his memory is excellent, which means he can pull random knowledge out in a meeting which makes him a useful employee. On the downside, he really needs someone else to arrange his travel, and he never hand-writes (and relies on google spell correct). He does get taken advantage of because his diligent-ness means that people just hand their work over to him and he works all hours to get it done.
I do recommend IT as a career - DP started out in Testing (diligence again - learned by having terrible organisation). And being in IT myself, the thing is, lots of us have some slight... oddities... so being dyspraxic really doesn't stand out.
