For many years she worked with Earth's Best Organic Baby Food, integrating nutrition and product development. She has written numerous articles on children's health and nutrition for parenting publications. To some extent, this is understandable. To a certain degree you have to learn to live with this characteristic, but there are many positive things you can do to help overcome it. In the long run, the bigger variety your daughter has in her diet, the healthier she is apt to be, since she is more likely to get the nutrients she needs.
Familiarity is key.
Tasting the foods is important during those times, but if your daughter is gagging, then perhaps you will just have to stick with letting the food sit on her plate, or in the serving bowl. Also, let her know that she can spit it out if she finds it horrible. So, in your strategy to get your daughter to eat a larger variety of food, serve those foods often that you would like her to eat. Children do eventually outgrow this stage. It just takes patience and understanding on your part.
