What to do?

Following because not sure my first inclination is all that great (offering a meal with a couple kid friendly options with different textures and flavors like chicken nuggets, blueberries, cottage cheese, carb of choice and saying "this is lunch, you can eat some of it now or later when you're hungrier". If the kid doesn't want to touch it, cover it, put it in the fridge and offer exactly the same the next time they say they are hungry. Kids are allowed preferences (my SD is ASD and used to have texture issues) but they have to eat something from all the food groups.

Maybe have them help u cook, my girl helps me cook and when we done I say yay lets try it. She love to do pretend cooking 🍳
