When someone has an allergy to something, the safest treatment is to avoid that thing completely.
Lots of children have food allergies. The severity of the reaction may depend on the level of exposure. This can vary dramatically from one child to the next. Some reactions can be very serious and even life threatening, like peanuts.
There have been recent studies looking at children with severe peanut allergies who ate very tiny amounts of peanuts over a period of time. Some of these children were able to overcome their peanut allergies. However, this therapy has not been proven safe, so do not try it at home.
Parents of children with allergies must take special precautions to prevent their children from being exposed. This is not always easy to do.
Talk with your child's doctor to figure out what these allergies mean for your child and how best to manage them.
