everyday challenges with Autism

I love Isaac with my whole heart and soul and I wouldn't change a hair on his body except for his meltdowns/tantrums and wandering. Since his diagnosis I haven't had any respite care for him,only carer support and I only get 10 days a year in which we have to space them out so they don't get used up easily.
Isaac is frustrating with how he has to have everything in a particular way and I'm not allowed to touch his hair as he has sensory issues.he wont sit at the table and I cant get him to use the toilet as he has sensory issues with that too,feels like he'll be in nappies forever. Eventually I know he'll get out of nappies, but as I said eventually.
Isaac having Autism is challenging as he will never have a standard sibling relationship like I do with my siblings, but he has taught me to make the most of everyday so I guess there are pluses and minuses to having a child with a Disability.
 
Oh his hair desperately needs a jolly good haircut and im not sure if I could clipper his hair as he would go into meltdown mode
