Iver has had a peanut allergy since he was a baby. Following usual medical advice at the time, I think we waited until one year to introduce him to peanut butter (one of my all-time favorite foods, including one I ate regularly while pregnant and nursing!), but it was immediately met with hives, itching eyes, and (I think) later vomiting (as it has every subsequent time since). I keep hoping he'll outgrow it, as he doesn't seem to be allergic to anything else (besides dog saliva topically. He also did have a hive-like reaction to eggs as an infant, but it didn't seem to persist. He also doesn't really like eggs so we don't consciously have to avoid them. Baked goods are fine, and he can tolerate all kinds of tree nuts, like almonds, cashews, etc. without a problem). Neither K nor I have
any food allergies, although I have terrible environmental allergies (hayfever) in the spring months, so we find it odd (and unfortunate).
Every six months or so, I give him (who also has mild eczema) a small dab of peanut butter to see what happens (we always can treat it sufficiently with benadryl or an antihistamine. We have an epi pen, especially for travel, but have never had to use it)... and it's usually met with a reaction like "Mama/Papa, my throat feels itchy!" One time about a year ago at a party, he inadvertently ate a pretzel stuffed with peanut butter and had a violent vomiting reaction! He definitely learned his lesson and now, he is very good about asking (if there is a new food, something on someone else's plate, or if we're at an unfamiliar location) before eating something, "Does it have peanuts?"
Kelvin thinks his allergy is not one to take so hard (I feel
so sad that he's deprived of PB &J, nutter butters, Reese's peanut butter cups, and other delicious peanut-y goods, while Kelvin reminds me that Vietnamese children and many other children worldwide survive just fine without this American staple!). We are lucky in that he doesn't have a severe anaphylactic reaction, and although his school is not nut-free (nor do I personally think schools should have to be to accommodate the rare students who react mildly), he only occasionally will get an itchy eye from cross-contamination at the lunch table. However, despite my crossing my fingers and re-trying peanut butter periodically and him being exceptional in many ways, it seems mostly likely that, at this point (at three and a half), he will probably be one of the majority (80% or so) of kids that
don't outgrow the allergy.
Niall, however, may be a different story. In recent years (and in between kids), there has been quite a lot of information/evidence put out there (like
in this New England Journal of Medicine article/LEAP study), that early (4-11 months) introduction and consistent administration of peanut-containing products actually may decrease the incidence of peanut allergies in kids (and, it follows, later in life). It was an interesting observation that Israeli kids that lived in Israel (as opposed to a similar population in the UK) had far fewer peanut allergies, which was hypothesized to be, in part, due to the widespread consumption of a peanut-containing snack, Bamba.
Bamba, popular in Israel, is a peanut-based puff product that is pretty darn delicious (if you like peanuts/peanut butter, that is)! We purchased a bunch of packets on Amazon and started giving it to (7-month-old) Niall last week, and he loves them (and has been totally reaction-free, although Kelvin, being cautious, wouldn't let me send him to school with any until today)!
Who knows if Niall is just not prone to allergies, a different baby/being altogether, or whether we are preventing a future peanut allergy in our #2, but we are going to try to keep up with the several-times-a-week
recommendation of peanut-containing products for the time being so that he, like I, can enjoy the above-mentioned treats as he grows.
(Poor Iver wanted to try some Bamba when I was feeding Niall, but, alas, it caused near-immediate throat itching for
him and required benadryl administration last night. He's gotta stay (pea)nut-free for the near future!)
