From my understanding, the most harm can occur from the ingestion of actual honey, say, from a spoon. Eating something such as Honey Nut Cheerios would not present a problem. Egg whites should be avoided for the first year of life. If an allergy is developed before the vaccine, it makes for a difficult time immunizing baby. As tasty as it is, peanut butter, and peanut products should also be avoided in very young children.
Young children have more of a tendency to develop an allergy to peanut oil.
This allergy can act very quickly, causing swelling of the throat and difficulty breathing. It is important to begin new foods properly. Do not offer several new foods at once. If you are going to give baby some banana, keep it simple, and watch for any type of allergic reaction over the next few days. Once you are confident that baby handled her new food fine, you may move on to the next.
