flagbabyds...ROFL! Let's not say that people with celiac disease don't have strong opinions!
The thing is, if you're new to this whole thing, this sounds like a reasonable question. It's that "diet" word that throws people. Eddie, for me and my kids, this is how it worked. When first going gluten-free (and I mean within the first week) it didn't seem to make a difference whatever the amount of it accidentally eaten (it was a touchy first few weeks with my kids.) I'd even say that for the first few weeks, it didn't much matter. Now, however, that we've pretty much removed gluten from out diets (with the occasional accident) and have healed in some very visible ways, a little bit in my daughter, for instance, will have her throwing up in half an hour, but otherwise nothing else
obvious (little = a bread crumb.) A lot of gluten, however, will have her throwing up, having intestinal cramps and major flu symptoms for 3-5 days (a lot = a bite of a cookie.) It really is a poison to us, even though that sounds so dramatic.
Good luck in working this out! I swear, it does get easier!
