Food aversion therapy is by no means an easy thing to do. Children don't want to eat the foods they don't like (go figure!). So, we trick them, soothe them, cajole them, reward them and somehow many of them try and then eat heartily foods that wouldn't touch previously.
Here is a recent success. Three mornings a week, I do food therapy during snacktime with two 8-9 year old boys in the school attached to our clinic. Billy eats very few fruits, but he likes crunchy foods. So every day, I bring in an apple or pear cut 2 slices and then deliberately crunch on one slice while I put the other near his mouth. He can't resist. He still grimaces at the apple, so I don't make him eat it, just crunch on it. He loves to do that. And once in a while, he will chew and swallow a bite (with surprise).
A month ago, I brought in tangerines. I put a slice on my tray and had the boys practice cutting the orange. To my surprise, Billy started mashing the orange with his finger playfully. I did so, too. We made a mess and giggled. Then I encouraged him to lick his finger. We played with oranges a few times that week and then went back to apples.
Last week, Billy's mom caught me in the hallway, "I just have to tell you what happened! I was on the phone in the kitchen, when Billy came in. He took an orange from a bowl of fruit, peeled it and then ate the whole thing! THEN, he went back, got another one and ate part of that, too."
Success with oranges is very sweet!
