Hi
We’ve traveled to Europe many times with our five kids including our type one diabetic son (diagnosed when he was 10 yrs old) now he is 28 years old. Are you traveling to Europe from the US? Or is the cruise in the Caribbean or Bahamas? Time Zone changes can change the way she reacts, so lows or highs can occur at different times than normal. Sometime my son will go low in the middle of a transatlantic flight.
We always carry snacks just in case.
Chocolate milk is a good choice but if refrigeration is limited….
We always kept good chocolate candies on hand. We used Dove chocolate ( as brand example) as it seemed to both raise and stabilize his blood sugar. The darker chocolate is lower in carbs but seemed to work better. We just referred to the carbs per serving and gave him an appropriate amount. The chocolates are easy to carry in a mini insulated bag in a purse or backpack. Sometimes he’d go low as we were driving or walking around in Europe and the chocolate was a blessing.
Make sure you don’t forget any of her supplies at home! Make a list of everything. Check it twice!
My brother-in-law (also type 1) got on a flight to the UK then realized he only had his daypack of insulin and testing supplies. In the UK, pharmacies often have emergency diabetic supplies, so he was able to buy one of those. But brands vary and we’ve found it difficult to find exactly what we needed. My son dropped his syringe and the Spanish replacement had a one inch needle.
Of course, hand carry all her diabetic supplies, don’t pack in a checked bag.
Hope y’all have a great cruise!
