Hi There
My Son James has been a coeliac since 2005 and we were devastated at the time. He had to have a biopsy to actually determine the diagnosis and it came back positive. But now 5 years on we are managing to keep him on the straight and narrow and does not eat any gluten or cross contaminate. He did have a bad time once, when we went to the local chippy (a young girl there) gave us the wrong chips and my son was violently sick and doubled up in pain. Phoned to ask if we were given the wrong chips and they did actually admit their mistake. So we do know that he CANNOT tolerate any gluten. We do get bread, pizza bases, pasta, plain biscuits on prescription and if you go on the coeliac.org.uk you will see that they have a list of age groups and what you are able to have on script.
Hope this helps.
