Children only control 2 things in this world what they eat and when they go to the washroom. Why reward eating everything with a "treat" do you serve the food or do they self serve? Please do not say it is not doable because it is we do it with 91 daycare kids. What if a child really does not like a food and you make him have one bite and he throws up( have seen it happen) if someone were to tell me to have one bite of a Brussels sprout I would puke. If you are offering all healthy food then does it matter if he had one bite of pepper. Afternoon snack could be a veggie plate. offer yellow peppers every couple days and
Maybe he will like them one day
