My 3 year old's eating turned sour at 2.
She's limited to toast, sandwiches, yoghurt, cheese, cruskits, rice crackers,biscuits, fruit bars, pasta (I can at least pack them with veggie smuggling sauces), potato in most forms, nuggets and, as of the last few weeks, pizza.
Foods that she will sometimes be okay with eating are pumpkin, sweet potato, corn, peas, grapes, water/rock/honeydew melon, honey mustard chicken, rice, spinach & feta rolls, crumbed fish.
I've tried giving her whatever I cook and not offering anything else but she will quite happily go to bed hungry so that doesn't work
