Mine was never super picky but they all go through a picky phase around 2.

Don't react (harder than it sounds) when they refuse, and keep serving a variety, and don't serve replacement meals. My preschooler has absolutely turned the corner on several foods she used to refuse.

I just want to add that Satter only works if you're playing the long game. If your goal is to get them to eat differently tomorrow, next week, or even next month, it's not the solution.

Ellyn Satter has worked for me.

That worked for you!
