DD:
milk-- age 2* (asterisk is because this probably doesn't count as true tolerance, but as a very high threshold for consumption instead, and the allergy seemingly resurfaced and went low-threshold when she underwent SCIT for aeroallergens at age 6, and the threshold has never again been as high as it was between 2 and 6yo)
soy and wheat-- age 3.
oats, was briefly reactive about 26 months old, and also to other grass family members. I just about went around the bend at this point.
She also has reaction history to some odds and ends and some one-off reactions where cross-contamination just seems SO unlikely. Cherries and green beans are on that list, as are a couple of beans. We've been very cautious about "testing" those things, but haven't seen additional evidence that they are a true problem.
OAS-- to cherries, apples, pears, peaches, plums, apricots, etc. from about 4 yo until the fourth year of SCIT (so about 9-10 yo).
Me:
milk-- age 3-4 (?) There are indications that my reactions to milk may have been pretty dramatic. I don't have any surviving family to ask, though.
egg-- age 2 (but again, this is NOT normal tolerance-- not even now-- I tolerate baked egg reasonably well, and can push my tolerance pretty high, but it's not what other people experience. I can eat a slice of cheesecake or quiche... but only if I've been eating egg regularly. If not, I pay with GI symptoms in a pretty significant way. This is, ironically, how my emerging shellfish allergy was able to sneak up on me-- I kept ordering a shrimp omelette, and was thinking that the disorientation, diarrhea, etc after was "just my weird egg thing." Yeah, I know. DUH.
DH:
green beans-- age ~7
apples (not sure if this was OAS)-- ~10
Nobody in the family has outgrown anything to which they have anaphylaxed. We have all gone on to develop additional food allergies after outgrowing some, and some of those allergies are unusual (dye, oranges, other non-top-8), and others are anaphylactic (tree nuts, shellfish). We also do not seem to establish true tolerance to allergens through low-level (immunotherapy?) exposures, instead we seem to go the other direction or the threshold doesn't much budge. Nobody is sure if this is a particular genetic profile or not, but it would make sense if it were since we all three have a similar profile. DH and I are a similar ethnic mix, and both from very highly atopic families, so it's possible.
DD and I both have anaphylaxis Hx, and DH has severe rxn hx to walnut and soy.
