I didn't find this book helpful for my extremely picky 5 y/o at all. I also have one of Ellyn Satter's books- perhaps it would have been helpful if I had started her program when my child was 1, but by 5, it was too late and did nothing for me. The best program I've tried is Kelly Dorfman's in her book
What's Eating Your Child where you (or your child) select one new food a week, say grapes. Your child has to have 1 bite of the new food every day with dinner for a week. Just 1 bite. Using this technique, we've incorporated two fruits and one vegetable (which was huge for our child), however, it was a major battle every night. A year ago, my ped gave me the name of a counselor who specializes on food issues and of course, I never got around to making the appt. (we were dealing with other more serious health issues with our other child). I'm with you on making this my NY resolution and finding the name of this specialist.
Most people don't understand what it's like to have an extremely picky eater. My son will make himself vomit rather than try something new. It's a constant battle.
