DS1 had quite a severe egg allergy from being about a year old or so. Just before he started school he had a RAST test, which had gone down to grade 3, so they did an oral challenge, which he appeared to pass.
However, since we have been reintroducing egg his eczema has returned with a vengence and he has periodically been sick for no apparent reason. Anyway, the other day I decided to make a dairy free (ds2 has milk allergy) quiche for dinner and arrrrgh... DS1 ate some then started complaining his tongue was feeling tingly. He then projectile vomited everywhere. We gave him piriton and he was back to normal quite quickly, but at which point he said "oh yes, my tongue went funny like that when they gave me egg at the hospital". It seems he was so fascinated by what the nurses were doing he didn't like to say he was having a reaction .
So, anyway, it looks like he is still allergic to eggs after all . So back to the drawing board. One ds1 with allergies to egg, nuts, pulses, beans and kiwi the other with allergy to dairy and (I think) sesame. Oh yes, and a vegetarian in the house too (me). Mealtimes are such fun to prepare for when we need 4 different meals to cater for everyone.
Arrrrrgggghhhhh.....
