I'm a firm believer tastes can change. If we absolutely detest something, then I doubt it will change but if we're not fond of a food, we can acquire a taste for it. For example my mother used to make these great cabbage rolls. With 5 kids, she wasn't about to cater to individual tastes - what was on the table was all there was lol and I respect this philosophy. I only cater to specific likes if my child is sick. I didn't like those cabbage rolls, but picked and tolerated them. When I became a teenager I started to like them and now I love them.

Unless a child firmly hates a food, they can acquire a taste for foods they're not crazy about. This is why I gently encourage my girls to keep trying the food. My youngest didn't like lasagna 2 yrs ago and now she loves it. My girls like a wide variety of food, because I've always encourage them to at least try new foods. Unlike most kids they even like all kinds of seafood and vegetables.
