We had our yearly check-up today, and my husband asked about scratch testing for our almost-three year old daughter. The doctor commented that the odds of her having food allergies were very slight - that food allergies tend to happen to the oldest child in a family, particularly male children.

Just curious...anyone else found this to be true?

BTW, we asked about clinical trials and he said the ones they're currently doing are still pretty risky, and the anti-IgE trials are not active yet.

Yes and no. Logan is the oldest and he has the most allergies. Lauren is allergic to peanuts and shellfish. I suspect she has a few more allergies esp. enviros but she wasn't quite 2 when we tested her. I've heard the results are much more accurate after the age of 3.
The anti-IgE trials ARE active and being conducted a 5 or 6 facilities accross the nation including Boston, Denver and Little Rock. The trial are not open to children under the age of 12, though.

Christopher is my oldest child with the Peanut allergy. I don't know how true that the oldest one is the only one to have the allergy is. My brother however is the oldest in my family and he always had severe fish allergy that none of us had. However in the last 3 years I can not touch a shrimp without getting very itchy and hives on my hands.
My doctor told us usually blonde hair Blue eyed children are most likely to have allergies. for us true for Chris,but my daughter has dark hair and eyes and has terrible animal allergies.
As far as our 3 year old is concerned he has not yet had Pb sandwich or nuts because we don't have them in the house. I do think he bit a snickers bar one time at a party and didn't have a reaction but I panicked because of the fact that Chris was with me and i didn't want him exposed.
Take care claire

Hmmm. I find that odd that the doctor would say the odds are very slight. In both mine and my husbands family that theory is proved absolutley false...oldest daughter having severe allergies one one side and youngest boy of four having severe allergies and youngest girl having food allergies. How would birth order ever influence allergies? Unless of course, it has something to do with more food avoidance in subsequent children.

I am the youngest of four and have an allergy to shellfish - none of my older sisters have any food allergies (mine was discovered as an adult).

Nope - Kevin is the younger of my two sons. However, his older brother did have a whole laundry list of allergies when younger, but he fortunately outgrew them all.

Our daughter (almost 6) is PA/TNA...shes the oldest of two, my son (almost 3)has not yet been tested or exposed.
So oldest yes, not blond and blue eyed (seems like such an odd thing for a Dr. to say in this day and age!)
When did you or will you have the second child tested? We're thinking sometime this year before he starts preschool next september...any other thoughts on when to test?

I have four children...
#1 Son (8) is allergic to dust and cats (I think he may have outgrown these- tested when he was 6 months old).
#2 Son (6) (Asthma) is PA, also allergic to shellfish, cats, dogs, milk, eggs, apples, strawberries and a bunch of enviros.
#3 Daughter (5) (Asthma) is PA, also rice, white potatoes, corn, green beans, peas, milk, eggs, oats etc... and a bunch of enviros.
(These 3 are all dark haired with blue eyes.)
#4 Daughter (3) is allergic to peaches and lettuce and cocklebur weeds. (This is the one that the allergist thought we were nuts to bring ANOTHER allergic child into the world!) She IS blonde hair and blue eyed [img][/img]
So... I guess our family would not fit into the category of oldest being the worst. Or the blonde hair blue eyed one either [img][/img]

That birth order comment certainly isn't true in our family. My daughter (first born) is not allergic to anything. My son, however, is both contact and smell sensitive to peanuts. Also, he has brown hair and dark brown eyes. So, the blonde hair, blue eye comment doesn't apply to us. I wonder where the doctor got that from? It would be interesting to find out.

I can`t see the logic to the birth order thing, unless as another person commented, it is because you avoid allergenic foods with the second one if the first is allergic. My daughter allergic to milk, eggs, peanuts is an only child, but I as the second born used to be allergic to walnuts and outgrew it. Later in my forties, I became allergic to mango. My older sister has no allergies. There is also no logic to the hair and eye color, but for what it`s worth I have brown hair and hazel eyes. My daughter is blond with brown eyes. As far as anti IgE, my daughter`s allergist said they will be doing studies on kids in about six months. However, he does not want to put my daughter in the study, because the study requires after the IgE shots a food challenge with peanuts and he feels this is too dangerous. The good news is that IgE is expected to be available to the public (not in a study) in two to three years! Let`s keep our fingers crossed! While it may not prevent a reaction, it should lessen the severity so that the reaction might not be life-threatening.
