My son jacob will only eat two things,Peanut Butter and Chicken Patties(Though not together) I just put him on this multivitamin called Syndion,It is for Autistics and picky eaters,I've already seen improvement in his behavior so far,The website tells you what it does overall it's a bit pricey but worth it,It's a powder form and can mix into juice .Here's the website,www.syndion.com If you try it,let me know how it works for you!:)

If he has some real motivators use them here to get him to try more foods. Make the "try" a ridiculously small amount and reward him for trying it. I mean if you put one pea on the plate and tell him it is the food of the week that he must try. If he eats the pea, then he gets his favorite. The idea here is that if he tries it often enough there are some new foods that he will actually like. Or hide it in small amounts in the food that he likes.

My son's got THE most awesome teacher. The other day she had all the kids experimenting with different food textures in a fun way. They took an english muffin, put peanut butter on it, then made it into a face. Hair was tiny chocolate chips,eyes were blueberries, nose was candy corn, mouth was an apple slice and ears were bananas. Normally we have alot of trouble getting my son to eat fresh fruits, but he ate EVERYTHING.

Maybe something similar will work for you :)

My son jags on food. I went to a Feeding Class offered by my insurance provider. The whole thing was based on the book "Food Chaining, The Proven 6-Step Plan to Stop Picky Eating, Solve Feeding Problems, and Expand Your Child's Diet". It did help some. It's taking something they will eat and adding an element or changing it gradually until another food is added or substituted. That might be a good starting point. Ex. mac and cheese, change the mac to pasta with cheese, then try it again with diced tomato, gradually increase the amount of tomato, then try it with tomato sauce with cheese on top, until you get to spaghetti.

The other suggestions they gave were "Sneaky Chef" and "Deceptively Delicious" which is more about adding purees. (We are not there yet.)

My sister is an OT does is takes a paper plate- draws a line in the middle and writes first and then. She tells the kiddo- first we eat ...., then you can eat..... (The "first" food is new but not too far off from what they eat now, The "then" food is always a highly preferred item.)

Part of our son's OT Therapy is playing with food- they have to touch it before the will eat it. Taking bits of food and pretending its a mustache or earrings or a tongue. We try to get it in or close to the mouth. Don't make a big deal of any gag noises. The food ends up thrown out at the end of the session by placing it in his mouth and spitting or "blowing" it out into the trash.

Good luck, still fighting the battle myself- even with the classes.

I've got picky eaters....but it is texture issues we face. 2 of my boys won't eat meat...unless it is crock potted and VERY tender. They are not a fan of breads or sticky stuff (pb, jelly, honey, refried beans, etc). We did 'color days' when my oldest boy was really young...today, for example) we will only eat RED foods (watermelon, red peppers, etc), the next day would be orange foods (oranges, peaches, tang, carrots, etc.)And we went through as many colors as we could! He learned his colors :)
He learned to try a variety...but it was a sloooow process. We didn't force him to eat anything, just offered it. When he helped to prepare the meals we found he would try them better :)
