It isn't recommended HotI. The BT on it's own is not a full diagnosis and if you eliminate gluten, then to get an accurate diagnosis later she'd have to go on a "gluten challenge" diet for six weeks, which for kids includes eating 2 slices of wheat bread every day. For my mum, having even a crumb of gluten now makes her violently ill - upset tummy, cramps, bloating, diarrhea, sometimes vomitting. I could not do that to DD, for six weeks.

I'd rather have a full diagnosis...
