Yesterday I was going through a big bag of stuff we got from the food allergy walk. One item caught my attention -- a two-page handout from a local, very respected allergist who has started conducting a food desensatization program similar to those described here. It is for kids allergic to milk and/or eggs. Basically, it involves administering (under the office's supervision) a very tiny amount of the food (in a solution) to the child and, if the child tolerates it w/o a reaction, gradually increasing the dose over time until the child can tolerate a normal serving of the food.
Before reading this, I had no idea such a program was going on in our area. I called the doctor's office about the possibility of enrolling Ainsley and left a message. She might be too young -- the materials indicated they are looking for school-age children -- but she is so close (4 yrs old) that I thought it was worth a shot.
