The lamb is made with wheat flour, yes? Does the lamb physically change so that it is no longer bread in any way, shape or form?
Would you purposefully give your infant something that is slowly killing them, and causing them not to grow? Your attitude seems rather fatalistic. Well, if you die you die. It isn't about killing a person on the spot. It is about eating something that completely prevents that person from being capable of digesting any food they consume for weeks/months afterward. So no, my son wouldn't die on the spot from Celiac by consuming gluten. But if I chose to give him gluten, and my son doesn't gain weight, the state will take him away because I would be knowingly killing him slowly via malnutrition.
If this were about me personally having celiac disease, it would be different. If Taz was capable of making this decision on his own, it would be different. This is not about me, nor is Taz capable at 11 months to understand either his disease, or why he feels like he does. I have to decide as a parent what to do. I don't take this role as his parent lightly. I do believe communion is invaluable. But it is also triggering misery and verified weight loss in my son. He was over 14 lbs a few days before he had communion, he was below 14 after he had communion.
