"Offer him one bite every day for a week," suggests Alan Greene, M.D., clinical professor of pediatrics at Stanford University School of Medicine, in California. Research shows that eighty-five percent of little ones eventually enjoy the taste of a new food. So if at first you don't succeed, try, try, try, try, try ... again!
