:( Halloween has always been a favorite tradition for DH and I. We really want to find ways to share it with our dairy and nut allergic son but we're not sure how given that for most people Haloween revolves around candy and chocolate! What are some ways you share Haloween with your children with food allergies?

We love Halloween. Just found out that my kids have nut allergies so Iam also open to suggestions regarding Halloween.

Try to focus on events other than trick or treating. See if there is a local pumpkin patch with fun activities for the kids. I know around us Publix grocery stores or the YMCA have little activities for the kids.
Take him trick or treating & then after you get home have candy that he can eat already on supply & just trade it out for what he received.

For the past few years we have had a Halloween party for the kids on special diets (and others as well). Everyone submitted a list of what was not allowed, so all the kids food was able to be eaten by all. Those that weren't familiar with dealing with the crazy allergy issues brought food for the adults or salad, fruit, etc. You have to be pretty crazy to make a pumpin cheesecake without eggs (egg replacer), cane sugar (maple sugar), wheat (crushed maple buckwheat flakes), etc. KWIM...
We were thinking about the Trick or Treat for Unicef, but I don't think many people would be prepared to hand out coins rather than candy. We are thinking of buying our candy off our dd for $.05 each piece. Then she can go to the toy store and buy something and maybe donate some to unicef.

I am thinking of making a fruit man with a pumpkin for a head. You basically make fruit kabobs and stick them in the melon for the head. THen you use fruit to make the eyes.
I am thinking of making punch and serving it in a pumpkin half. Not sure how that will taste tho....
I am also considering making homemade marshmellows that are corn free. Who knows....
Having a bonfire is also a consideration...

FYI-
If you are looking for corn-free marshmallows, powdered sugar, etc, try a kosher grocery store/website around Passover (Easter-time). They make food just for the holiday that doesn't contain corn as it is not allowed.

My dd is 3.5yo and loves the idea of dressing in costumes and walking outside at night with a flashlight! We've been pretending halloween all year! Well...she also does not digest cane sugar well at all ( and we don't eat any hydrogenated fats, no exceptions). She knows she feels lousy on sugar...so I talked to her about this issue very directly. I said something like, "I know you want to dress up and go trick-or-treating with your friends and I want to do that too but the people are going to give us candy that has sugar and other stuff in it so we can't eat any of it." She just looked at me and said, "I don't want the candy." So I asked, "are you sure becasue I don't want you to be upset. Your friends might be eating it." She said, "I don't want a sick feeling. Will you get me some honey sticks?" I agreed and asked, "what will we do with the candy we collect?" She said, "I have no idea." I suggested we bring it to the local women's shelter and she said okay. I hope it all works this smoothly when the time comes. I am going to stock up on the treats she can have in the house...and maybe get a few little toys from the dollar store or something.
We're also really filling our time with other types of activities- carving pumpkins, making a scarecrow, etc.
Good luck everyone.

Thanks for the ideas every one! I decided to have a party :LOL and invite our freinds with allergies and those with out. We are having mini pumpkin "cheese"cakes, apple cider, and PB&J sandwiches cut in halloween shapes! DS is SO excited we are making the invites tomorrow. To help get us all in the spirt I made the boys a few halloween ponchos and hats they can dress up in to their hearts content(and boy are they puting some miles on them :) ). Thanks again your ideas have saved halloween for us! :throb

I think we are going to have a Halloween Hunt. I am going to hide candy in the yard (homemade candy) and give the kids flashlights to go find it in thier costumes.
