Siblings

DS (will be 6 next week) has MFA - DD - 3.5 has nka but we are avoiding several foods for her as well "just in case". I see a lot of people who have more than one child and it seems that if one has some sort of food allergy, they all do.

Since I have no intention of feeding her the foods and the allergist wants to wait until she is at least entering Kindergarden to have her tested, I try to remind people that she cannot have anything with peanuts/tree nuts. Fortunately due to another child in her class, her day care room is pn/tn free.

I'm wondering if I should get her tested sooner rather than later to be sure.

Any thoughts - I want to be sure that she isn't exposed to the foods before we test her and we find out the hard way that she is also allergic. The reason I bring this up is that she has a good chance of getting into the public school system for Pre-K in September through an inter-district magnet school program. Thanks.

I am not sure if I am the one to answer this...but this is what we've done. I guess the difference is that your 3.5yr old has no know allergies, my younger siblings did, so they were of course tested for those and the foods their older brother was allergic to. I think(if I were you) I'd talk with the allergist right before entering kindergarten to discuss testing and maybe a challenge to any of the foods your are worried about(like peanuts). My almost 4yr old is going to be re-tested and hopefully challenged(so far his pn/tn has been negative, but he's never had any either) but I'd like to know for sure before Kindergarten(for 504 purposes). When he enters preschool next year, I just use the phrase "we are avoiding all pn and tn because of his brother's life threatening allergy"...I spoke with the director, they are fine with that idea.

Anyways, not sure if anyone will agree with me or not, but I would want to know *for sure* before entering Kindergarten....so I think testing beofre is a good idea. I hope it all stays negative for you, good luck!!!

I'd go forward with the testing. Trust your instinct.

We had our 2.5 year old tested a few months ago for all peanuts and tree nuts due to the fact that our 5 year old is allergic to both.

My 2 yr old tested neg to all, however, I have not gotten up the guts to try anything on him yet. I may ask the dr at my older son's next appt if I can do it in the office.

My husband and I wanted to know either way. Regardless of the results, our home has stayed peanut/tree nut-free. It just makes it slightly easier on play dates, b-day parties, etc. when it's he and I alone and not with our older son.

Does a skin prick test show positive if it's a first exposure?

I just had my 4 year old in the allergist this week for testing. His 7 year old brother is PA.

It came back negative. He has never been exposed to peanuts or tree nuts. He is not allergic to anything else and does not have any seasonal or pet allergies.

The allergist did suggest when he will be going into the first grade and eating in the lunchroom that we do a food challenge there so they can moniter him.

She also told me they are now recommending that you wait until your child is 4 to introduce them to nuts or peanuts. I guess this will be something new they will be announcing.

I would wait on giving nuts or peanuts, just my opinion.

We had our 2 1/2 YO DS tested 2 months ago- his sister is PA, TNA, soy, and egg. He was negative for all however he has never been exposed to Peanuts or any tree nuts because of her allergies. So we will be restesting him in August (when he turns 3) and right before he is to enter preschool. Our allergist said that if he passes the SPT then he will be taste challenged in the office to clear him before school starts. I really wanted him tested for my own piece of mind before he started preschool. So now we are just waiting to do it again.

I thought that you had to be exposed first for a test to be positive...I remember asking my allergist to test him for foods because I was worried...he would not do spt because it could expose him. He was only 3 and we were testing environmental allergies. I may be wrong, but I thought it was the same as for a bee sting. Most people do not react the first time they are stung. It is the second time that a reaction will occur?

I do think having a reaction the very first time exposed is rare(but I could be wrong as well). I have been testing my almost 4yr old every year, even though he's never eaten it. I am hoping that *little* exposure from the scratch test will be enough for his body to decide if he is or isn't allergic once we do the challenge. BUT...like my pa son, he had eaten pb crackers many times prior(like over a 3-6mth period) before he had a reaction) so I guess you never can be too sure, but you can try to figure out what you can ahead of time....

hmmm! I thought the same thing. First exposure you don't react. But my son did react the first time he was stung. He was probably bit before his first reaction to a bite -- but I'm sure I would have known if he had been stung previously because it really hurt. Odd.

This is why I am unsure...my 1yr old was given a strawberry newton, for the first time, and she started screaming and pulling at her tongue. She also got some small bumps around her mouth(I gave Benadryl and it stopped after 20 min)....but that was the first time she'd had strawberry(she usually eats just baby food)....we're avoiding for now!!

When you say that you are avoiding allergens with the younger child, to what extent are you going? Are you feeding nothing that's made on shared equipment, avoiding x-contamination possibilities in restaurants, etc.? I ask this because, if she's never had any exposure to the allergens, my understanding is that she definitely will be negative. It takes at least two exposures to trigger an allergic reaction (it can be many more than two exposures before the allergy develops). If you've always followed as strict precautions to avoid the potential allergens as if she actually had the allergy, I don't see how the testing could be a valid test whether she's actually allergic because she hasn't had that first exposure.

My 7 year old has PA, and I brought her younger brother in at 18 months. We'll get him checked annually--He's 2 1/2, so far, no allergies. It can't hurt to test them this young, my daughter had the allergy at that age. You just may get a false negative, which is why you should keep re-testing until they're about 5. If he does test positive, I would want to know sooner rather than later.

My oldest, 6, is ingested, contact and airborne to peanuts with a host of other FA. My 3 year old is only allergic to weeds. We have had her tested twice. My feeling for getting the tests are that she is now participating in play groups and we have left her with a sitter when we have taken DD6 to plays and the like. Although our sitter is VERY aware of the possibilities, I feel better leaving her in cell phones off situations. DD3 still avoids anything that has caused her sister to have anaphalactic reactions (99.999999% avoidance). We are also going to do an ingestion challenge at the Doctor's office before she starts school. She will still never take or eat a PBJ, but the oops factor will not be the same as with her sister.

I will say it was so strange the first time I left DD3 with just a snack bag and a change of cloths--no epi, no benedryl... It almost felt 'normal'

Our allergist told us that the whole "had to have been exposed first for it to show a positive" theory was untrue. I am not saying whether he is 100% correct, but he was adamant that a SPT was not necessary when testing our younger son for FA. He had an immunocap and tested negative. Also, my PA son absolutely reacted to his very *first* exposure to pb, he was only 11 months and had never been exposed before. My friend's child had an anaphylactic reaction to her very first taste of pb, again that time it was her very first exposure.

The idea that if one sibling is allergic the other one will be is not accurate (IMO) - they have a higher likelihood, yes, but of all the PA kids I know in our school community, they are the only one in their families with the allergy, none of the siblings are PA.
