As a mom with a 4 year old who is SEVERELY allergic to peanuts, these statements really concern me. Millions of children who are perfectly healthy in every other way, have food allergies that can cause a life-threatening reaction. Food allergies claim over 200 lives and are responsible for over 30,000 emergency room visits each year. Peanuts (peanut products) are responsible for 80% of food allergy deaths.
Now I am not a parent who tries to control what other parents feed their own kids, but all I ask is if you do eat something that could possibly KILL someone else, please practice good hygiene AND don't do it in a very public place. Peanuts/peanut butter has protein that can leave residue on things that my son may touch like handrails, seats, tables. I make every effort to teach my son to basically not touch anything and we wash hands VERY often, but other than wearing surgical gloves, it is impossible for him not to use his hands.
Not all food allergies will cause DEATH but peanuts is definitely one that has the very real potential to. Peanut allergies are on the increase and that is NOT media hype. I never knew anyone with a peanut allergy until my son was diagnosed with one. Now there are 3 in our family and all children. Do I lock my son in a closet until they find a cure? Of course not! I will try to provide him with the closest thing I can to a "normal" life. One very important reason we vacation at Disney is because they understand the severity of food allergies and strive to provide the best options for those with them.
To the pp, I hope that no one in line around your DH would decide to pop open a container of shellfish and start handing it out to their kids and have their kids put shellfish residue all over the same environment your DH will have to share. It would be a scary experience for your whole family to endure in the happiest place on earth.
Sorry about the soapbox but having to worry about a food killing your child every minute of every day is stressful and to encounter others who are not willing to put theirselves in your shoes and be considerate to the safety of others is disheartening.
