Thank you for your message weluvgators, very helpful
I have taken Charlie to the doctors this morning for reassurance as his stools are still far from solid She said it sounds a bit too much of a coincidence for it to not be the noodles that have caused his tummy troubles but we are to take in a stool sample just to check for bugs!
Charlie has made it clear he doesn't want to go back to the base which is understandable but there are occasions when he is going to need to go. I may send him with a pack up. The doctor seemed to think this was a good idea not only to ensure the food he eats is gluten free but also for him to regain confidence in what he is eating is ok.
