How to get your toddler to eat food 😭😭

This is starting to worry me! My almost 3 year old hardly eats.. she’s such a picky eater that all she would agree to eat is noodles, pizza and sometimes chicken wings. Nothing else! This breaks my heart having to give her the same thing every single day just so she would have something in her stomach.. she refuses to eat anything that isn’t one of those three. I don’t know what else to do! Her Mealtime is stress time for me. Her doctor keeps saying “it’s just a phase... she will outgrow it”... it’s been two years! 😭😭 has anyone experienced this? Would she eventually stop picky eating?
