Look, I studied child development in college. What we learned was that food should never be a battle with children. Children are people too. They have their own taste buds. Their sense of taste and smell is way more acute than an adult..
And so you allow them the "opportunity" to eat new things, but you do not force or insist.. You offer the opportunity..
You cook what you are going to to cook. You offer at least 1 item you know they will eat. the other items can be new or things they have not been willing to try in the past.. and then you let them be in charge.
With our own child we learned that a small salad plate or bread and butter sized plate with a small fork.. was more palatable than a luncheon or dinner plate. It did not look so over whelming.
An example. She liked all types of salad foods and "Plain" vegetables, grains and meats.
So if I made spaghetti. I would grate zucchini and or carrots into the sauce.. Wheat spaghetti.. no butter or oil.. and place a TBL spoon on the plate of each in different piles. Then a few carrots, some lettuce or spinach leaves and some celery, maybe a few fresh cooked peas or green beans..
IF she ate something. I would quietly replace it with another spoonful. .. No conversations etc..
She did learn to eat many things by being in day care. They would keep a record each day of what the children actually ate each day.. Lima beans, beets, Turkey meatloaf.. These were things she never tried at home.. But sitting there with her little classmates.. they just ate what was there because they were all eating it together. ..
I also did not keep anything in the house I did not allow her to eat. So we had baked goods, ice cream, holiday candy etc.. But it was not a lot of it and not all of the time.
No bribing, pleading, insisting or punishing about food.
Now some children for whatever reason really need control and since eating is something they can control.. Rewards can work..
I came up with "Brave Tasters" for some neighbor children. .. The parents were so upset that they "could not get their kids to eat dinner"..
I felt the mother was a terrible cook..(she even admitted, she hated to cook). So many casseroles made with cream soups.. Yuck..Even my husband and I would blanch at her food.. It all looked like blobs.. on the plate. Lots of canned vegetables. Our daughter never was served canned vegetables or fruits. But this is what she knew how to cook,,
"Brave Taster" is a chart with stickers. IF your child tries some new food. They get a sticker. Once they reach a goal.. (7 new foods or whatever the parent thinks is fair. ) the child gets to request what is for dinner.. Or gets to help make dinner or gets to pick a place to eat for a meal.. (Parent comes up with a reward.)
This gives the children that need an incentive to at least try..
FYI all of these children by the time they were in middle school, were willing to pretty much try any type of food. Our daughter is crazy about cooking,,, she now has to sometimes convince us to try new foods!
ha.. Pay back.
I think many parents just want to see their kids eat. They take it personally that their children do not like the food they are served each night.. Moms feel like they are not doing a good job..
Guess what?.. Even after planning, purchasing and cooking a meal, even I sometimes do not want to eat what is for dinner.. I will just have a bowl of unsweetened cereal instead..
