Oh, ds1 has a huuuuuge list:
Top of the list is reserved for the dreaded and horrifying ....... chocolate! He can't stand the smell, even if someone is eating it in another room. Bit of a problem really, as his mother is a committed chocoholic (although fortunately for him I have been sworn off the stuff since mid-June).
Then we have:
Peas
Sweetcorn
Potatoes
Omelettes (He found a minute piece of potato in one once and that was it.)
Nuts - taste, texture or smell. Although we have found that since he's been having ground almonds in all his gluten free baking, he will now eat the odd almond.
Peanuts in particular - will run from the room screaming if someone else has them - apparently its the smell.
Bananas - this is oddly recent, but suddenly they make him gag - which is really strange, because he adored them right up to a couple of months ago.
High pitched whining noises - like the one our blooming gas meter makes in the living room and the one his radiator makes in his bedroom. 
Anything strong smelling, ie perfume, deodorant, air fresheners etc
Having his hair washed or brushed.
Water on his face.
Ice Age - the movie, well any movie actually, but Ice Age is the one that started it all (and they always seem to have it on in Paediatric Outpatients when he has an appointment - I'd almost swear they've made a note of it
)
Any story, book, programme or song where someone or something gets left behind or someone leaves at the end. He says people always say its a happy thing, but its not, its sad and they will never have that thing/see that person again so its actually 'devastating' (his word). He told me this is why he can't stand me to sing Nancy Spain to him anymore, even though it was his lullaby as a baby and also why he had a complete meltdown when we tried to introduce him to movies gently by putting on Laura's Star (the star goes back to the sky in the end and everyone is happy).
And a very odd new one he told us about this weekend was, he hates looking forward to things. He can't explain why, just that it makes him feel funny and he finds it distressing. I assume this is somehow to do with the need instant gratification.
I could go on - but I'd take up the whole thread!
