Tomorrow, LBA will see a new allergist. We learned when he was just about 18 months old that he was allergic to peanuts. I may have let him have a piece of my english muffin that had some peanut butter on it. The tiniest morsel made it into his mouth and suddenly he was wheezing and flushed. Off to the emergency room we went. So he was indeed allergic to peanuts. When we went to the allergist is was also determined that he was also allergic to pistachios. His allergies are slight - he can be around the nuts, he just can't eat them. He knows this and knows to ask about things before he eats them.
To my knowledge, I have only one allergy - it's to penicillin. As an infant, I was given penicillin and broke out in a roseola rash. The family doctor decided it was easier to just declare I was allergic to penicillin and I haven't had it since then.
I read somewhere a while back about the "explosion" of childhood allergies and how it might have come from the exponential rise of anti-bacterial soaps and lotions. It is believed that we are washing off some of the "good" bacterias that help us to fight off reactions to items that are introduced into our bodies.
Mrs. BA and I are hopeful that LBA grows out of his allergies (it appears that SoBA is not allergic to anything). Let's see what the allergist says tomorrow.
