A., I can remember being 15 years old and my mother was still trying to stuff calories down me because I was so skinny. I never liked food, only ate barely enough to survive, but as it turned out years later, I had a lot of food allergies. Believe me, now that I'm much older, I have no problems liking food or putting on pounds (unfortunately). I suggest you do see a doctor who will test him for food allergies and if you cannot find one, do some internet research on it yourself. Better that he's a little skinny now than overweight. Do not, I repeat do not give in to the temptation to just stuff him with sugary foods to make him gain weight, though. If he's eating healthily and getting enough vitamins and minerals through food, it shouldn't matter that he's a bit skinny. The problem with sugary foods is that by feeding him more sugar laden foods now, you can actually trigger an addiction to sugar in him which could cause him all kinds of health problems. For me, I always liked raw foods -- raw carrots, celery, even barely steamed green beans, white rice with a little butter, salt and pepper -- and still do -- mostly because those foods never have caused allergic reactions in my stomch! Since he's too little probably to eat very many raw foods, try just steaming lightly, leaving them just a little crunchy. His distaste for foods could have a lot to do with texture, as well as taste. And like I said, he very well may have some food allergies that are causing him to dislike the fattier foods you've tried thus far. Since young children need milk, you do need a good sub for that. My oldest daughter was just like me about food, but she loved cheese (and still does), so I gave her plenty of cheeses to make up for her dislike of milk, but you have to be careful with that, too, and not give him too much of it. Have you tried macaroni and cheese? Most kids love that and I think even one year olds can eat it. Don't worry if he doesn't love a lot of variety; just make sure he gets enough minerals and vitamins from what he does eat. With time, he'll like more foods. My daughter grew up to become a gourmet chef. I now will eat anything that isn't nailed down, but still dislike the foods I am allergic to and I stay away from those. Good luck with your picky eater!
