Interesting read.
We've been given the medical advice to strictly avoid a long list of foods (for my DS). At times I have the urge to just see if he could take a food...these temptations have grown recently. BUT then he accidentally got hold of a cold cup of tea, didn't drink it just touched it. Immediately got hives over his face and body, his eyes swelled up and his nose ran like crazy. Thanks goodness he didn't drink any! This incident really shocked me (no exposure for 9 months) and brought home the importance of following medical advice!
