Holidays abroad - Rules LOL
1. Always take twice as much of everything as you think you'll need. OK so you'll bring tons back with you, but that beats the alternative and insulin just isn't available anywhere as far as I know, without a prescription.
2. a) take a list of medications - do you get a tear off strip on scrips, which show all your listed 'repeats'? - if so, that will do fine, otherwise a letter from GP on their notepaper.
b) also take a letter from GP (or hospital) saying that you will e carrying sharps. Cos when you get to check-in they will ask you if you are carrying anything sharp. You will say Yes, and then they ignore it in my experience. If not, produce letter. Mine is 16 years old this year LOL
3. Invest in a Frio or two in case you don't have access to a fridge - big one for supplies and small one to carry with you for short acting pen. Need to be rehydrated every day or two, leave the one in your accommodation in the coolest darkest place - I have found right at the back of the wardrobe is usually that place on most holidays.

4. When it's hot, insulin is absorbed MUCH more quickly than normal, especially if you are doing stuff like swimming and other activity - including dancing, but of course that might be doubtful given his age! Therefore you need to test test test, and also have hypo remedy immediately to hand at all times. 100ml of full sugar Coke = 10g of Carb. Available everywhere!
5. Enjoy yourselves and don't panic !
