Hi A.,
My first response to you didn't go through, so here goes try #2! My 4 year old daughter has peanut and treenut allergies. Her only reaction so far was one year ago when I introduced her to PB for the first time. She presented with severe abdominal pain followed by vomiting, some coughing (which I think was due to her crying excessively and the fact that she has mild asthma), and skin discoloration. We now carry an epipen and benadryl tablets at all times. Although I'm a little calmer about things now (vs. a year ago when I posted my own question here), I go between being really anxious and a little bit anxious regularly). She saw an allergist shortly after her diagnosis and we now have an emergency/action plan at home and in daycare/pre-school. I plan to ask him about the necessity of a medic alert bracelet for when she goes to kindergarten.
Frankly, I'm not quite ready for that transition yet! Her school is supposedly nut-free, which gives some reassurance. Having said that, I had to educate them that many of the products they use are "manufactured in the same facility as/on the same equipment as" nut-containing products. I'm also had to ask them not to allow her to have any special treats that parents bring in for their children's b-days, even if they are well-meaning and really believe that they are nut-free. We keep special treats at school for those days. When she goes to public school, I'll have to deal with educating teacher and dealing with the lunch-room etc. I know that there are different schools of thought about whether or not putting children at allergen-free tables is doing a service or disservice for them in the long run.
Have you gone to this website yet? www.foodallergy.org They have a lot of useful information.
On a personal note, I'm continuously struggling with how to educate her about her allergies in an empowering way vs. a frightening way. I just recently told her about the epi pen, but haven't gone into a lot of detail. When we go to special events (thanksgiving, b-day parties, etc.), we bring a special dessert that she loves and can share with others. I also remind her that she needs to check with me (or Grandma, etc.) before eating anything other than what we've given her). I want her to feel as included and normal as possible, but still make it clear that it's ok to ask people whether or not there are nuts in foods and to alert people that she has the allergies. At three, I bought the Bugabees (friends with food allergies) book, which we both really enjoy reading/singing along to (found on Amazon). It's perfect for young kids.
I'm also trying my best not to avoid all unfamiliar settings (where I can't completely control the food situation) since for a while, my tendancy was to not go altogether (and that's not how I want her to be as she grows up). I find that the more calm and disclosing I am (such as telling people about the allergies in advance so that we can choose a restaurant that will have more "safe" options and getting my brother NOT to put pistachios in his stuffing at Thanksgiving), the more I'm able to enjoy the outings.
I hope that you and your family have a happy Thanksgiving!
