it is (going on how dd1 is when she has an infringement) awful, becstarlitsea. I hope you can find the cause.
dd1 follows a very strict exclusion diet - no gluten, casein, msg (even naturally derived), or sweetners in particular. she also cannot tolerate most perfumes/aromas, so has very neutral soaps etc.
she is severely ASD, and following this diets has helped her enormously.
We rejoiced when we found genius bread - at last, a GF bread that was not too awful. dd1 seemed to like it (beofre she wouldn't really eat bread at all), and so we were happy she had extended her diet to include another food.
we went to a party where, very kindly, the hosts had bought some gf food for my dds. this was when she first had the dieatry specials rolls. I thought it could well have an effect, but her general diet had been good, so gave it a go. to my absolute astonishment, despite her eating these, adn then a couple of gf cakes (we try to avoid sugar too, but hey, it was a party!), her poo the next morning was the best it had been in a long time! (sorry to be graphic)
so I began to test - observed her poo (nice!) and assessed for a few days. then gave her a genius bread sandwich. following day, horrific results - rancid loose stools.
so, banned genius bread agin, it took over a week for her stools to even approach normal again - when usually a diet infringement would take max 5 days to return to normal. I double checked the ingredients - all seemed fine (in fact, genius bread has fewer suspect (for dd1) ingredients than the DS rolls!)
I went through the above again - introduced genius bread, same horrible results. back to DS rolls, and poo is fine. I have no idea why, ut for now the DS rolls work for dd1.
If you are going to try mixing your own flour, I can recommned these people
the flours are absolutely definitely pure when they say they are - the exclusion diet dd1 follows is ridiculously stringent, and the AiA/Respectrum requirement on cross-contamination is second to none.
