I come from a family with a history of CD that goes back at least 3 generations. My history started 40 years ago, so my understanding of how to manage my CD has taken about 20 years of trial and error.

It is important to understand that each affected person is very likely to have different symptoms and need slightly different management methods.

That said your number one priority for you and your children is to get gluten free immediately!!! Without doing that first - all your other management activities will be unsuccessful!
And I suggest that you do not try any supposedly gluten free products. Just go to a ‘Neanderthal meat and potatoes’ diet. Grass feed beef, wild caught fish as a protein source and organic veggies cooked simply without sauces or gravy. Avoid poultry and pork and butter and eggs because they are often grain fed.

Finally, look on the Net for any CD sites that have lists of safe foods as a place to expand your food variety.

And, be aware that the full benefits of going gluten free will take as much as 6 months.
