Have I solved our nutrition problem?!?!

I have three kids. Talia is a good eater. Recently she has become eager to try new foods. Shayna, so far, has not refused any foods at all. Whatever you give her, she will eat. Then there is Alex. He eats pretty much nothing with nutritive value. He subsists on yogurt, bread and chocolate. I read somewhere about a disorder found in little boys in which they slowly and systematically cut out more and more foods that they previously liked. I think he has that disorder. He used to eat peanut butter. Then he would only eat it on Uncrustables. Now he won't eat it at all. He used to eat cheese sticks. He doesn't like them anymore. As I said, it's only yogurt and bread. The bread shouldn't have crust and yogurt, for the love of God, should only be the "smooth" kind with no "freckles" in it.

The interesting thing is that Alex is my sous chef. He loves to cook. I bought him some kiddie knives and he helps me prep everything. He is the head salad dressing maker. He cuts the cucumbers. He won't try anything. I know I'm not supposed to make a big deal out the eating issues. I rarely mention it. We eat dinner together as a family about 99% of the time and I want it to be a pleasant experience where we talk about our day and enjoy each other's company. Ron, Talia and I model varied, healthful eating. We encourage and reward trying new foods and mostly ignore the rest of it. Maybe it's about control but Alex is so easygoing in every other area that it doesn't make sense.

Most of the time I just ignore it, as I said. I know people who ate nothing but pb&j their entire childhoods and they are fine (and more adventurous eaters) now. Every once in a while I panic about the whole thing. He's not underweight or anything, I just worry about him missing some essential nutrients.

Recently I bought a juicer as a gift for myself. Alex, ever my helper, happily pushed all the fruit and vegetables in. Miraculously-- he drank it! Through juicing he has now had his very first carrots! He had a pear! and a lime! and oranges! and apples! and blackberries! I'm going to try to move into juicing veggies a little bit more and see what I can get him to try! It's very exciting!
