How old was your LO when they were diagnosed w/the allergy? How bad was the first reaction? And did you get a blood test done? And if your kid is 6yrs or older, did you repeat the blood just to make sure even though the 1st blood test said it would be a
lifelong allergy? Just wondering because I heard that about 20% of kids with peanut allergies grow out of it by 6 or 7 years.

Re: Peanut Allergy Moms
My daughter was allergy tested at about 18 months for peanuts and sesame seeds. She never had eaten peanuts, but one day I had peanut butter and I kissed her--and she developed a single hive on her forehead.
She gets retested for her allergies every 3-4 months (eggs, peanuts, and sesame). She will be going back in about 2 weeks to see if there is any change.
He was 2 at his 2 year check up. He got rashes when he ate peanut butter. Nothing too bad, but he tested positive on both skin test and blood test. We will test him when he's older to see if he's still allergic. Our doc said there's a chance he outgrows it, but I'm not holding my breath.
We'll test dd eventually to see if she's allergic or not, but until then, it doesn't matter since we keep her away from nuts anyway.
He was 15m when he was Dx'ed. He had been seeing an allergist since 10m, but the testing at 15m was actually done as part of a BFing and Child Health study my twins and I participated in. He tested positive for peanuts and eggs on the skin test so they followed up with a blood test. (That's also how we discovered my other son's egg allergy so it's a good thing we did the study!) On the blood test, he was positive for peanuts (moderate) and negative for eggs (which we confirmed with a food challenge).
At follow-up when he was 2.5 though, he tested negative on the skin test for peanuts. We ended up deciding to go ahead and do a food challenge at the allergist's and he passed it and has eaten PB ever since. He had most of the risk factors for NOT outgrowing it so that was a very pleasant surprise. (But then, a year and a half later, we learned the hard way that his twin had developed a serious tree nut allergy, so we're back in the land of epi-pens.)
I pushed for an allergist referral at my DS's 9 month appointment bc he had had some reactions to rice cereal and sweet potato as well as "baby cheetos". All digestive except for baby cheetos. We thought he was allergic to those and wanted to know how badly. We had been dealing with eczema since day one.
Turns out none of those he is allergic to via scratch test, but he is severely allergic to peanuts, mildly to cats and fish.
from what I understand peanut allergy is not one you can outgrow.
