I was out and about yesterday with my three year old twins and one of them got a few blotches on their face and one hive on forhead. I sat and thought about that for awhile and today it dawned on me that I have NEVER given them peanut butter or anything with peanuts because their older brother is so allergic.

They have never been tested because they don't have seasonal allergies, (exima(sp?), but my older daughter has that too.). My question is, do I have hubby buy a reeses peanut butter cup, wait for my allergic son to go to school, have benydryl and epi jr's on hand (I have like 4-5 of them that are good) and have them take a tiny bite?? Is that stupid? Or do I have them tested??

I can share what our allergist said when we saw him last week. We were there for my PA 3-year-old, but I also asked him if and when my 8-month-old should be tested (no known allergies yet). He didn't say when he should be tested, but said we should avoid giving him peanuts until age 4 and that he should be tested before we try giving any to him.

Great topic.
Sorry you had mystery hives!
I will tell you my experiences after I go to the allergist's office next week with Joe, my three-year-old. I feel like I need to have some type of "all clear" before I send him to preschool in the fall. I wonder if they'll do a SPT? I will report back by Feb. 1.
- Nate is 6 and has peanut & penicillin allergies, mild persistent asthma and eczema.
- Joe is 3 and has reactive-type asthma and undiagnosed (but not severe) environmental allergies. He didn't have much eczema as a baby. He has no known food or drug allergies BUT has never had any peanuts.
- Drew is my 7-month-old with mystery reactions.
I'm glad you asked this question, because it's hard to know what to do.
Say that you find out the sibs are not allergic to peanuts? Do you take them out once a week and intentionally feed them something with peanuts in it? Or do you just go about life as usual, living as though they ARE allergic?
How do you handle preschool food and snacks for the non-allergic sibling if you're not feeding them peanuts until age five or so? Do you still send all snacks from home as though they are allergic?
Great topic.

Just want to second what April said about this being a great topic. I also just reread my post and realized it was very brief--I wanted to add that I'm sorry you had that incident and I hope you get some answers. I think I'm just starting to realize how many things will need to be thought through for the second child--even before we know whether he is allergic. Thank you for posting this, and I hope everything goes well!

When an older sibling has food allgeries, I think many allergists recommend younger siblings avoid the allergenic food. DD#1 is almost 11 and PA (discovered at 19mths). DD# was treated as PA from birth and finally tested at 5.5yrs (SPT, food challenge). She is not PA. The house is still peanut free, but DD#2's kindergarten class is not. The non PA status for DD#2 certainly means less 'worry' with her regarding food situations. She is allowed may contains/processed in a facility products and bakery products. She does eat peanut butter on occasion, and I do watch her when she eats it.
Personally, I think if anyone is concerned about younger siblings and allergies, they should take them to the allergist to get tested. Then deal with everything (if anything) afterwards.

Timely topic. Our DD, 7 has allergies. Our DS, 5 does not. I just had our DS, 3 Rast tested last week and all tests came back negative! What a relief! Yes, he has been exposed to the foods our DD is allergic to through my breast milk when he was an infant for about 1 year. I was suspicious that he did because he had ezcema until I changed my diet to eliminate what our DD was allergic to.
I am now much more relaxed about sending him to pre school as well as other group activities.
I have always allowed our 5 year old the freedom to eat and be in contact with things our DD is allergic too when he is not at home. School and friends houses mostly. He even made a gingerbread house with his class this year. The difference is that he gave the house to a friend and he had to change his clothes before he came home from school.
He has eaten peanutbutter at school, not at home and he had to change his clothes in the basement when he came home.
He is learning how to keep his sister safe - a lesson that will pay off when they are older.
Keep Smiling
DD - allergic to peanuts, tree nuts, coconut, and egg

Hi All,
My older son (who is 5) is PA, TN and kiwi allergic. He was diagnosed around 18 mos age. Our allergist and pediatrician told me when our younger son turned 2 to have him tested. We just went through that last week. He is now 27 mos old. All skin tests came back neg. The allergist still told us to avoid the foods as much as possible until age 3 and to keep peanuts/nuts out of our house for good. We have decided that our older son's rules to keep him safe and healthy are the rules we live by and that's that. This negative test result did not change our ways at all. It just helps me relax a little when I'm on my own with my little one out and about.

Have them tested. Definitely do not try self testing at home. Even a first time exposure to an allergen can lead to anaphalaxis - that happened to my friend the first time her toddler tried pb. Even with an Epipen, you wouldn't want to subject your child to that, and a trip to the ER.
I have an older PA child and a five year old. Our allergist recommends avoiding allergens until after age five for siblings. I did need to get him tested before he started school at age four. I had him rast tested, because a SPT is an exposure and I did not want him exposed. I know that other posters do feel that if a child has not been exposed to an allergen that a rast is not conclusive, but our allergist was firm that a rast would confirm any allergies. I believe that, because I know my PA son tested positive on his rast to many things he had *never* been exposed to! Younger son tested negative. I am still not feeding him pb until he is past age five, but he eats may contains, bakery foods, things brought in by classmates, etc.

I guess I'll call the allergist today and make an appointment. Even if they aren't allergic to peanuts, we will remain peanut free. My son is so sensitive that I can't have the other kids have it in their mouths and get even their spit on him later. (Ate a spring roll once with the sauce with crushed peanuts, kissed my boy about 1.5-2 hours later when I got home, perfect lip print blotch on his face, eyes swelled!! Couldn't believe it.) So we are peanut free anyway. Just curious how to figure out about my other kids!!
Thanks for all the great feedback!!

I just wanted to add that I don't think their (the 3yr old's) preschool is not peanut free, but it is suggested that snacks bought shouldn't contain peanuts. I don't think people are reading labels, just not sending peanut butter cookies. They may however buy something that "may have been processed". My twins haven't had reactions. But if one is allergic, being identical, the other one probably would be too. I am calling dr. office right now!!

I haven't read the other rplies just yet...but I would talk with the allergist and see what they say. My current allergist told me to wait until Carson was 5 and then we'd try some in the office. In the meantime, we've been checking his blood and doing a scratch test each yer, negative so far. My youngest has also been tested for peanuts once(blood and cratch) and so far negative. I had eaten some while prego and nursing though(before it really sank in that it was a BAD idea), so she has been exposed. Alot of times they won't reatc the first few times anyways...I did daycare and served peanut-butter crackers over many months(no one was allergic, parents all said okay) but my son reacted one day to pb-toast....if I had to guess, I'd say it was about his 10th exposure to it. Good luck!
edit...Boomer, I have a friend across the street with twins, one boy one girl and an older sister. Only the boy twin and the older sister are peanut allergic, the girl twin is not!
Chanda(mother of 4)
Sidney-8 (beef and chocolate, plus MANY seasonal)
Jake-6 (peanut, all tree nuts, eggs, plus seasonal and animal)
Carson-3 1/2 (milk, soy, egg, beef and pork, plus animal)
Savannah-1 (milk and egg)

I have 4 kids. My eldest was diagnosed as PA (MFA actually) at 3 1/2, and Joey (my second oldest) is only 2 years younger, so until he was about 1 1/2, he had been exposed to a small amount of peanuts prior to that.
Joey got introduced to peanuts at preschool, because I forgot to tell the preschool that we weren't giving him them. He's never had allergy testing done because he seemed to have no other allergy problems and his eczemaa was so very mild. He's never had a lot of peanuts, tree nuts or shellfish, but he's had some exposure.
We've avoided peanuts, tree nuts and shellfish for Allison (third child). She had some allergy testing done... to confirm milk and dog allergies and to try to pin down whatever else was making her eczema flare so badly.
Ryan is 1 year old, and I plan on keeping him off peanuts, tree nuts and shellfish until he starts preschool. The only exposure he's had is through breastmilk. (I eat shellfish and almonds at restaurants when Jason is away for the weekend).
Cheryl, mom to Jason (9 MFA including peanuts, tree nuts, shellfish and egg)
Joey (7 NKA)
Allison (4 milk allergic, suspect shellfish, avoiding PN/TN for now)
Ryan (1) nka *knock on wood*
