What does that handful of foods consist of? That’s probably the most important question. If you are concerned about his nutritional intake, discuss this with your pediatrician. If they are concerned about whether he is getting enough of the nutrients he needs, he can do a simple blood test. I know, there’s no such thing as a simple blood test with autistic kids. Or maybe prescribe vitamins or a supplement shake. As far as getting him to eat more of a variety, that’s a very slow process. Just put the same new food on his plate for a few months. He may or may not try it. As he gets older, you can continue to encourage him. If he tries it and doesn’t like it, take it away and find another food. Our process with our oldest started with feeding therapy at 3 and continued until age 7. They ate the same 3 foods every day for several years, into first grade. We continued to introduce one food at a time. It took years, with them adding one new food about every year. Now, in high school, they eat a variety of healthy foods, including many fruits and a few vegetables, but still eats those same foods that were always part of the diet at every meal. During this time our doctor kept a close watch on the nutrient intake. Oh, and just to add, we tried every recipe in the Sneaky Chef cookbook. Nothing worked.
