let'ssee. My son has smelled like:
Fish...carnitine supplements
poop...I Tell you, his hair/skin/sweat/breath when not freshly washed smells like poop. He gets frequent baths.
some odor I can't identify
sickly sweet urine/skin.
also that tart smelling urine that comes from proteinuria.
(his breath has been horrid from various meds in the past.)



and then he also smells like the million other 'additives' he self-applies to his body in the course of a day oh! oops, that's irrelevant to this question....but true.
