Hey Forkie...you've got some amazing suggestions here, and I'll be saving this thread for my DSs!
Please don't feel like you're not spending enough time...the suggestions you've been given will have happened over weeks/months/years.
I have four DC so know that feeling...sometimes I think it helps as I do forget that there are things that are more tricky for my DSs, however, in life they'll have to learn that also, and we tend to try to have a giggle a lot at home at and with each other, so when one just falls over for no apparent reason, the others love doing action replays and we all laugh.
Of course in an 'unsafe' environment among strangers that would be really upsetting for anyone, but at home, with love, I hope the boys learn to be able to approach difficulties with good humour.
OT has been brilliant. Also I have found the sports and hobbies they like, and have made it clear for the other ones it doesn't matter.
My boys hate football, they would hate to be in a very alpha male school. But ime schools are good at offering a range of activities. I have told them I don't care if they don't try at football and in winter made sure they had thermal vests on as they got cold from standing still!
Three/four years in to our first diagnosis, and it is fine. Their diagnosis is so much part of who they are, that I can't see where one stops and another starts.
I have found scooters so useful, as both get tired quickly walking, one in particular, and scooting is def easier for him (or me dragging him along!)
I hope you find your GP helpful...we were overseas during our diagnosis which also helped as it meant access to healthcare through comprehensive insurance.
