I'm almost entirely plant based and despite this, my child will not go near a vegetable. It's reached a point where I use extra vegetables when I make stocks because she will eat soup, but only if it has meat and no visible vegetables. Putting extra vegetables in the stock likely accomplishes nothing but it makes me feel a little bit better.
I've gone so far as to watch exotic cooking shows on YouTube with her to see if any vegetable dishes or different ways to prepare them are interesting. I deserve a fucking Michelin star with all I've learned about cooking vegetables for her. Despite this, vegetables are bad and "Mmmm actually, kids don't have to eat vegetables."
