There is a theory out there that says chances of allergies grow the earlier that certain foods containing protein are introduced. Because infants still have immature immune systems their bodies are more likely to produce an allergic reaction.

The chances of outgrowing the allergy depends on the food. If a baby has an allergy to peanuts, tree nuts, fish or shellfish it is very rarely outgrown. Other allergies though like those to milk, eggs, berries etc can be outgrown but not every person will outgrow them. if the allergy is still present at about 12 years old the chance that it will be outgrown is slim.

Other foods will only produce a reaction if a certain amount of the food is ingested. this is generally more of an intolerance though.

I would say no because I have heard it is better for children to have an allergy than for an adult to develop one because it is more than likely they will out grow it. My son is allergic to corn and had a milk allergy when he was born, the milk allergy is gone and he is almost 10 months old but we are still waiting for some good to come out of the stupid corn allergy that is a hard one to deal with.

If an infant has any kind of reaction DO NOT give that food again. Do not give a baby any food on the allergy list. Yes it does increase there chances of having allergy’s. You are supposed to wait at least 2 year before giving them the food on the list (shrimp, peanuts, strawberry’s, etc). Yes it does increase there chance of having a permanent allergy.

Some babies can have an allergic reaction to a food and then as they get older the allergy goes away while some remain. My oldest son was allergic to blueberries then around age 3 the allergy just disappeared. My younger son is allergic to peanuts and that is an allergy that rarely ever goes away. Some allergies are genetically passed down so they are born allergic.
