Every time I see something about picky eaters, I think, so what if they are just picky? It's still an unpleasant sensory experience. Yes, it can be a problem when a person's list of acceptable foods is extremely small, and yes, it can be a problem when they can't find anything out of the available menu to eat, but it's not the world's worst problem.

Also, I was seven when I realized that if my father or mother didn't like something (say, liver or brussel sprouts), we never had it, whereas I was routinely forced to eat food that made me gag. My mother did, by the time my younger sibs were old enough for it to matter, accept that there was no point in making someone eat food they hate, but it was a journey.
