Andrew Sieber had known since he was a kid that he was allergic to peanuts. His son, Ethan, was a toddler when he had a severe reaction to a peanut butter cup in the Halloween candy. Given the family history, it wasn't a huge shock to Ethan's parents. But they were surprised by the severity of their children's allergies. All of them have some form of severe allergy, and two of the Siber boys, Ethan and Jacob, are diagnosed with what's known as EE — eosinophilic esophagitis. It is an allergic inflammatory condition that can make the esophagus swell. It can make it hard to breathe and swallow food. But researchers and a support network at Cincinnati Children's have made the condition more manageable for the Siebers. They say they're lucky to have specialists in their own backyard.
