Since first pregnancy fourteen years ago I have not had an anaphylactic reaction, swollen lips, the big 'golf ball' lumps (can't remember the name), dermatographia (when you get weals from pressure), aquagenic urticaria (water 'burns'), 'poached egg eye (allergic conjunctivitis when the white of the eye swells) or dyshidrotic eczema (small fluid filled blisters on hands).
I do still get itchy eyes, sneeze a lot, get rashes, dyshidrotic blisters on the soles of my feet occasionally and wear gloves a lot to reduce contact dermatitis. Always carry allergy eye drops and anti-histamines and never far from an EpiPen. No longer have the epinephrine inhaler (adrenaline).
My immune system is -fucking weird- unusual and although the stopping of the major shit could just be coincidence, the immunologist told me that pregnancy (and breastfeeding) can be a bit of a 'reset' as such, as your body has to learn to tolerate an extreme 'foreign body' for an extended period.
Because of my issues, I was really careful feeding/weaning both ds. The first one was exclusively BF for six months, weaned on one new thing every three days, and BF until 14 months. No allergies at all. The second one (was 5 months PG when stopped feeding first) was again BF exclusively for 6 months, then reacted (rashes both ends) to absolutely shit loads when weaning - the no more than one new thing every three days make it really easy to identify which fruits, vegetables, eggs, chocolate etc that cause the issues. once again meat was fine. He's grown out of everything now, apart from a bit of a rash from tomato and he has eczema and asthma.
Allergies have moved on a lot. 15-20 years ago a lot of people hadn't heard of anaphylaxis and allergies were rare. No child under the age of 11 had died (their hearts cope better with the blood pressure drop). I don't know the stats of the last 20 years, people are more aware and cases are in the media, but it's too difficult to find reliable statistics now as there are too many agendas out there.
Sorry that this has turned into an epic essay, if the op can take away anything it's that allergies change over time. It might get better, it may get worse, it may be that you decide that taking a risk and eating out for a special event is worth a few days of possible upset stomach (massive assumption, but IME extreme allergic reactions are resolved quickly).
