When I was little, I had times where I just straight up slept at the dinner table because I refused to eat. My parents learned quickly that if they didn't want me to starve to death, they were gonna need to make foods I actually liked.
Once they'd been doing that for a while, I got a lot more open to trying new foods, even ones I didn't like before, because now everyone else was eating and enjoying food I didn't have and I wanted to be a part of that. Didn't make me automatically like everything, but it did open me up to a lot of healthier options.
