I know EXACTLY how you feel- you have described my son L (Aspergers) as if he were your son!
He can tell the difference between types of potato...so if i can't get King Edward or Maris Piper- i might as well not buy any- he WILL not eat them.
A FANTASTIC book- which i got out the library.....
CAN'T EAT, WON'T EAT........published by Jesicca Kingsley publishers-
fantastic.... all about kids with ASD...so sympathetic to the sensory issues.(described my son in there too....picks crumbs off everything-craves salt)
Best bit i learnt was the letting the child smell,touch,lick the food- and building up through this over days/weeks to the point where they tolerate it in their lips- then bite it- chew it- and even spit it out into a tissue.....
through that book got L to 'tolerate' no more than 6 peas in a meal...i have agreed to not add more...and we are now working on him tolerating food on his plate that he hates....or has too much of....so that if we are eating out and they add peas/salad etc...that he won't start running wild.(last year i was sooooo proud- he agreed to try a burger at a pub as he liked the look of it in the picture menu...when it arrived it had sesame seeds all over it.....he went beserk. tried using my roll bottom as a replacement top- but he refused to even try it. since then he refuses to eat burgers anywhere but hom.. (i see this as 'fear of the unknown)
L is now 8 and we still have awful trouble eating out etc....but at home
he will eat Choc spread sandwhiches
Toad in the hole
yorkshire pudding
100% beef burgers in a roll (only cooked at home though!) NO onion!!!
Ross Grill Steak
egg-sized ammount of mashed potatoe
same ammount baked beans
Asda value rage pizza (NO green bits!!!!)
4 or 5 slices of carrot once/twice a week(slices size of a 2p...chopped up into tiny bits)
NO FRUIT AT ALL
....so he doesn't even get 5 portions of fruit/veg in a month let alone a day
NO EGGS
Cheese has to be melted...so wouln't eat a cheese sanwhich - but loves cheese on brown bread toast
NO puddings/yogurts- yet will eat sweets/chocolate
Infact THE ONLY MEAL WE ALL EAT THE SAME OF is Pancakes....sugar and lemon!!!!
So appart from the fruit/veg....i accept now that though we cannot 'simply have a meal' that there are enough foods he will eat to keep him growing!
You are right though- when people see what he eats as a cooked meal- they comment- but i am hardening to that now- as at 8 i still have to feed him anything he is 'scared' of- and the act of feeding him gets more attention that WHAT i am feeding him...he is not embarressed that i feed him- and i tell onlookers that if i didn't he wouldn't eat....as though i say he eats all those foods above- in reality HE doesn't FEED himself with all of them.... if i were to say the food he will eat himself- then the list would be
Choc spread sandwhiches
Toad in the hole
yorkshire pudding
100% beef burgers in a roll
cheese on brown bread toast
Pancakes....sugar and lemon!!!!
oh and he loves sugary milky cups of tea....well that is the only way he will take milk....so i try to convince myself that the calcium intake outweighs the sugar!!!
so hope this reassures you that i truly understand.
