Thanks to candy companies like Spangler and many others, we don't have to get sick on Halloween from gluten contaminated candy. (This picture was too funny not to put up! :)
There are so many other great companies that offer gluten-free candy as well. I think every child deserves to have normal holidays. On Halloween, this means eating candy like it's going out of style! Us parents need to do the studying before hand to find out which candies will be best for our gluten-intolerant children. In doing this, we can have those candies on hand so that we won't have to spend our Halloween telling our sweet kids, "No you can't have that, no you can't have that..." and so on. Have a stress free holiday by taking a look at this article and current listing of gluten-free candy.
