I was never a picky eater as a kid. I ate sardines and brussel sprouts, no complaining, even if I didn’t like something very much. I’m not picky now, either.
My niece and nephew and their dad are very picky eaters. I just don’t understand people who are picky, and especially those who won’t eat certain desserts! I mean, is there really such a thing as a bad cake? It makes family gatherings a PITA for the host.
I think the only thing I would absolutely refuse to eat as a child was liver. I had my other preferences, like many kids, some of which my mom would cater to - raw carrots or turnips (easy to accomodate), no butter on sandwiches or under peanut butter - but generally I ate what was put in front of me. Like many people here the rule was that I had to at least try something a few times before I could refuse it, and that was a privelege to be used very rarely. I learned to like or at least tolerate most things. As an adult there’s still a few things I really don’t care for - liver, cooked turnip, squash or sweet potatoes. Otherwise I’m good with just about anything.
Oh, desserts? Just keep butterscotch away from me - never liked it and I never will. And I was never particularly fond of anything with raisins in it.
