My mother was diagnosed with celiac disease in 1954, very shortly after the disease was even discovered. She lived her life with it, although was told she had outgrown it, and it wasn't until 1986 when she was 34 that she finally was re-diagnosed and learned that had been what had made her so ill for her entire life.
In 1986 celiac disease was still virtually UNHEARD of - she used to mail order rice bread in at about $8 per loaf and it took 6 weeks for it to be shipped in, making eating bread a luxury. Same for rice pasta. People used to give her a hard time thinking she was "dieting" not "on a special diet" and as she was very thin, she often felt ridiculed. As a result from these difficulties, she became very active in the national Celiac Association (Canada) and worked hard on education, research into foods (ie/ contacting companies getting ingredients lists, pressuring companies to make gluten free alternatives, working on trialing new recipes at home and adapting foods with gluten free ingredients, etc. She also worked hard on petitioning the Cdn gov't to consider celiac disease a disability, and provide a tax break to make up for the added expense of gluten free food).
So, I lived the majority of my life in a household with a celiac, at a time when little or nothing was known by it in the general population. I read lots of books, went with my mom to visit speakers, helped her in the kitchen, lots of things like that.
In a long round-about and indirect way, celiac disease is what caused my mother's death just a few years ago. I have always made it a priority of mine to help people out with what I know as a way to honour my mother. So, although I have no experience of dealing with childhood celiac disease, I do have a good bundle of knowledge and resources, and am more than happy to help out if/where I can!
(As an aside, I am keeping my son gluten free until 12 months. My sister didn't with her children, and they are all fine, but I just have a nagging worry in the back of my mind. Although, that said, today I decided to try oatmeal, as it is occassionally tolerated by celiacs as sometimes in the milling of the oats, the gluten containing part of the oat is eliminated.....so I gave it a go, and will see how he is!)
