Anyway, all of this led to both of my boys being tested for sensitivities to food/environment and both boys had a TON of sensitivities, including gluten and dairy. This happened right before Thanksgiving.
My oldest is 4 and in preschool on Mondays, Wedbesdays, and Fridays. Three days before Thanksgiving break I explained to both of his teachers that he had a bunch of allergies that I was previously unaware of and I would be providing his snack from now on. I also told them I would bring in a list of allergens for them as soon as possible. Monday went fine, but Wednesday one of the teachers was gone. I picked my son up and he said "guess what I had for snack!" and I guessed the foods he had in his backpack. He said "nope! I had regular snack!" I immediately went back into the school and asked his teacher, who confirmed he had regular snack. She claimed she forgot and since I hadn't brought the allergen list she thought it was okay. I told her I had said I'd provide his snacks and he had one in his backpack, and she said "yes I saw that but I only noticed when we were packing up to go home." - even if she had forgotten before, she noticed at the end of the day! It upsets me a lot that she didn't say anything!
My son doesn't have physical symptoms, although the gluten allergy has him underweight and his skin color is off since it was blocking nutrients. He withdrawled for a few days because it was acting like a drug to his body. An allergic reaction lasts up to 4 days and he had JUST PASSED that time, and then he had to start over again. The past two days have been hell! He is acting out, crying over everything, and throwing fits. I am INSANELY frustrated but I like his teachers and his school :( I sent in the list of allergens today but if this happens again I think I will need to say something...but I don't want to get her into trouble, both of his teachers are awesome. Sigh.
