Yeah, kerosene, to give you another reference point, the kids who go into the feeding clinic often start out only willing to eat toast, chicken nuggets, french fries--and literally
nothing else. Or sometimes it's textural, like they'll only eat mashed potatoes, applesauce, sometimes a banana, and nothing else.
For my stepson, it's barbecue sauce he wants to put on everything in order to make it palatable (including mandarin oranges, of all god-forsaken things.

) But as long as he's eating the green beans, barbecue sauce or not, we don't care.
