Hi
@1claire
I have been travelling as a type 1 diabetic for years ( too many to remember)-- I always carry all my supplies with me in my hand luggage -- the thought of any necessity being lost as part of checked luggage is ... well.... unthinkable.
I am travelling to Italy in 45 hours and I will be carrying all my pump supplies , insulin , spare insulin pens , test strips , spare meter , spare pump manager ( a bit of kit that runs my pump ) , 1/3 of my glucose supply -- I do pack some of the glucose -- cuz let's be fair -- we can buy orange juice or similar pretty much anywhere
hope this helps -- and have a lovely holiday -- and DON'T worry !!!!!!!!!!
edit to add -- get a letter from your DSN ( Diabetic Nurse ) stating your son has D and needs to carry all the gear ( just in case )
