Hello, all. I have lurked here for almost a year but this is my first post!

I have 2 boys. the almost 5 yr old has nka. the soon to be 2 yr old is allergic to milk and peanuts. He is anaphylactic to dairy and has contact reactions. We discovered his peanut allergy with a SPT around age 1 after his ana milk reaction.

Although he was exposed to peanuts alot through my breast milk (bad mommy didn't know any better [img][/img]), he has not to my knowledge had any traces or may contains of peanuts/nuts since the diagnosis. His SPT was positive as I mentioned ( I don't remember exactly, but I can remember that the wheal was not terribly big at the time.) A few months later he had a RAST immunocap done and it showed him neg for peanuts.

We have continued to treat him as though he is allergic and eliminated as such.

Here's my question. He has an appt with the allergist just after his 2nd birthday. It has been a year since his last testing. There has been some discussion about doing a challenge at sometime since his RAST was negative. I'm not sure how I think about this.

Yes, part of me is thrilled thinking there could be that remote chance that he has out grown or that the SPT was a false pos and he never was allergic, But I'm scared to death to think about a challenge. Esp given the severity of his milk allergy.

I'm going to request repeat testing at his next appt and depending on the results, I was wondering what you guys would do? Would you consider a challenge? Part of me wants to wait at least another year until he's 3, but another part of me thinks it would be good to know one way or the other if he is really allergic or not now. KWIM?

Thanks for any input,

It is generally recommended these days to wait until a child is 3 or 4 to introduce peanuts to him. So, me personally, I would not do any food challenge with peanuts until at least age 4. (but probably request a skin prick test first). That's what I would do.

Hi, and welcome. I think that given your hesitancy I would wait. I have learned to follow my instincts, and if it scares you, don't do it.
As far as the breastfeeding, you are not a bad mommy. I breastfed both my boys and only one is pa. I ate pb with both, so you never know what causes it, but I dont believe bf does.

Hi and welcome,
I think I would hold off on the food challenge since your son has never ingested peanuts until age 4 as well. My ds has never ingested either. He has very high RAST and skin test results though. I was told by my allergist that he has a better chance to outgrow it since he's never ingested it.
If you do the challenge, and he fails it, you've now given him peanuts, maybe limiting his chances of outgrowing. I imagine how tempting it must be...just think though: 2 more years of wondering vs. potentially having an allergy his whole life. Just my opinion [img][/img]
Try not to beat yourself up about the breastfeeding and eating peanuts. There's a BUNCH of "moms beating themselves up" threads on this board on this topic if you want to see how you're not alone.
Personally, I was unable to breastfeed and I have twins, one w/multiple allergies, one w/none. I question any link between breastfeeding and allergies too.

thanks ladies.
It is tempting to find out one way or another but I agree, why risk ruining the chance to totally outgrow it eventually. It's not like it's been that hard to avoid so far. Most things containing peanuts or a may contains warning are already ruled out due to the dairy allergy.
It would just be nice to be able to give him some of the things I've found that are dairy free but have that darn old may contain peanuts/nuts warning on them. Oh well.
It would also be nice to know just how careful we have to be as he enters the 2 yr old class at day care and eventually pre- school.
As for beating myself up over the bf thing. Thanks for the support. I'm way over that. I know I most likely didn't cause his allergies. he had the genetic bomb for that from his dad and a little from me too. Being sensitized through bm probably helped us to figure out his allergies sooner and thus start eliminating them sooner. maybe in the end it will be a good thing and he will out grow the PA since he's never actually ingested them himself. ( we can only hope ?!)

I would probably wait until 4 to do the RAST again. That's how we handled my youngest son (no food allergies). We treated him as if he were allergic but knew he had to be tested before starting Kindergarten. So we had him tested at age 4 and the first peanut RAST was negative. We retested at age 5 this past April and again the RAST was negative. Then we did a skin test in the office to peanut and 19 other foods he had never eaten. All were negative.
At that point the allergist said we could do an oral challenge in his office. My son ate Reese's pieces over set intervals for an hour and a half duration. No reactions.
IMO, your child immune system is still maturing. There's not a big reason to test unless you send your child to preschool. If you always have an epi, treat him as if he were allergic, there's no compelling reason to test until he/she goes off to school. Unless it's for your own peace of mind which is certainly understandable. However, given the fact that RAST tests are not scientifically perfect, I think I would hold off if you've gotten a negative score for the first one.
Editing to add that our allergist insisted that a second RAST be done before an oral challenge. He has seen negative results one year, only to have a positive result the next. This is why we did second RAST, skin test, then oral challenge in office. If the RAST was negative, skin test was positive, we wouldn't have done the oral challenge. He said both had to be negative for him to consider doing the oral challenge in his office.
