Yes Debra, my son has a peanut and brazil nut allergy. When we first arrived and went to the Pole Vie Locale to register him for junior school and for the school cantine, I told the assistant about the allergies. Initially she said he'd have to see the school Dr but I had the letters from his consultant in England which she could understand. When he started school we were again told he'd need to see the school Dr, despite providing the evidence and treatment plan from the UK. In short, that consultation never happened and about 6 weeks later I got a projet d'accuiel individualisé direct from the school Dr, with the treatment plan copied from the UK document. He changed to college in September, and before he started friends told us that, like your son, he'd have to see an allergiste annually for tests and that we'd need a new PAI every year. In the UK we were told quite correctly that these allergies rarely go away and they only retest once, usually at 12 years of age. This is partly to see if your child is one of the rare few who loses the allergies, but mainly to reinforce the need for care as the child is going into adolescence, so they don't become complacent. Seeing an allergiste annually is quite frankly a waste of time and money, except of course if you're the allergiste!
Anyway, before term started I went to the college and saw the head teacher, who speaks fluent English and was very helpful. I showed her the PAI I'd received 3 months earlier and she just said it was fine and she passed that onto the cantine. No need to see anybody for this school year at least. OK, they know I'm a Dr and that might have made a difference, but I think it was more that the head was helpfully pragmatic. I will strongly resist taking him to the allergiste next year either. Aside from being completely uneccessary, apparently in France they take loads of blood tests and have never heard of EMLA (the local anaesthetic cream we use a lot in the UK before taking blood from kids - much kinder). As with you Debra, I know what he's allergic to, and don't need it to be ritualistically confirmed. I haven't pulled the 'je suis médecin' card yet, but I certainly wouldn't be scared to if it meant my son avoids uneccessary medical intervention.
