I don’t know about anyone else, but before we had Tim and had to deal with allergies first hand, I knew that anyone with an allergy would be covered in rashes, probably be violently sick, worse case scenario anaphalytic reaction.
Then came Tim which definitely changed our views as he had none of those symptoms.
The other thing that I am sure people not dealing with allergies are unaware of. They can have different reactions to different things, again something that we are slowly learning.
We are now starting to understand that reactions to soya affect his eyes, causing conjunctivitis looking reaction.
We think it still affects his stomach and mood as we had a few days of him seeming generally unhappy and reached the stage of him becoming inconsolable one afternoon, finally resulting in a dose of piriton. But the main visible reaction is the sticky eyes.
