WOW! Thanks! I was not expecting so many messages Thank you.
OK, I have calmed down, spoke to the doctor today and here's the update:
According to the RAST test, DS has a severe allergy to: dust, mites, cows milk protein, fish, nuts and above all to soya and egg.
We have decided to ignore most light to medium intolerances and only avoid the grade 4s unless we see a big change in DS health for the worse. So, added to the list above are: Lentils, mustard, kiwi and Sesame seeds.
DS is going to have an iron suplement as well as an allergy prevention treatment which would be basically having a tablet a day.
Dr expects that in 8-10m the allergen antibodies would be nearer to an acceptable level (currently DS's count is 7x the normal).
I am expected to convert most of my house to a monk's cell, no curtains, carpets, furry toys, pictures or anything that may catch dust.
Need to find a new house for my dogs (snif) unless they have minimal contact with DS .... long shot but I'm going to try to find them a foster family to spend the winter with. Once summer is back they spent most of the day in the garden so they should be fine and maybe DS's defences will get better by the time. Obviously if the dogs (and the foster family) are very happy with each other, I would just let them go.
About the good news, DS is not allergic to glutten! yipee! so he can have pasta, normal bread, etc . I feel relaxed just to be able to forget about the long list of intolerances for a while. Obviously we will need to adapt our food and the way we cook it. So, I am going to take the offer of those who offered their knowlege about "free-from" recipes so, if you know of any child friendly easy to cook recipes which doesn't contain milk (or its derivates), egg, soy, fish, nuts, lentils, mustard, tomato and sesame seeds, please let me know.
Thank you again, you all have been very very very helpful.
