Absolutely, especially my DS11. Super-sensitive to smells, and a super-taster. And I agree, I don't really think of this as a gift, as it has a lot of limiting consequences, though DS become much more able to cope as he has gotten older. When younger, he was unable to sit at the table if we were eating certain foods (particularly fish or eggs, but many meat smells and some intense spices) and even had a strong gag response to several of these. He can smell things long before any of the rest of the family as well. He also comments frequently on scents, often ones which are pleasant to him (often things which have either very subtle or non-description smells to the rest of us- his favorite blanket, that "mommy" smell which is not perfume or anything intentional on my part, etc.). He is also able to detect (and refuse) very minor changes in recipes.
