When:
We discovered Ina's allergy when she was about 2 1/2 months old. She didn't gain any weight from 1 month 'til 3 months as a result of her allergy. Ped diagnosed the allergy (she was nursing enough but not gaining, per LC assistance with pre-and post-weighs; plus the green poops, allergic shiners, red ring, and reflux). A month later added all legumes, eggs, and wheat to our list.
She outgrew dairy at 19ish months, soy also around that time (legumes also were safe by then). Outgrew wheat by the time she was 10 months. Still reacts to eggs and is now on an epi for them (no ana reactions yet).
With SJ, we avoided eggs, peanuts, treenuts, fish/shellfish throughout the pregnancy. And quit dairy, soy, legumes, and wheat the last month of the pregnancy and didn't try any of them again 'til she was 4 months old and thriving. She is fine with me eating wheat (and fine with wheat herself now). She reacts to cow's milk (which we didn't try 'til she was 6 months). As a result, I still haven't tried soy or legumes and won't be trying eggs in my diet or hers 'til she's 2 or her sister outgrows her egg allergy, whichever comes first (I hope

).
I take probiotics and am eliminating dairy, soy, eggs, legumes, peanuts, treenuts, fish, shellfish.
I've posted here occasionally and learned a lot here, just don't seem to come to this forum as much as others, I guess because I feel like we've got a pretty good handle on things at this point.
ETA:
My family has a history of food allergies (I have uncles allergic to seafood and bananas; and my dad is allergic to MSG and soy, but none of us 7 kids reacts to anything).....
Also, Ina was on 100% neocate while I pumped when she was recovering from hospitalization with the allergies/reflux cascading, and more neocate after that (with supplemental breastmilk) while we rebuilt my supply (damaged by supplementing, retained placenta, and EPing). The Ped told us that her allergies had cascaded to the point where she couldn't digest any proteins at all, thus the elemental formula 'til she healed. We successfully returned to 100% breastmilk and she nursed 'til she was 2 1/2.
