I doubly recommend Calorie King and My Fitness Pal to track any treats or meals out. Will you be flying? I only ask because you should carry a note from your provider. It's standard and just states that your child can fly with insulin, needles, or a pump.
Another thing I like to do is research the local pharmacies. We use CVS, so it would be easy if we needed an emergency script called in. It helps if you already know which # you'd need to give in case of a situation like that.
The final thing I keep in mind is that travel, exciting activities, change in routine, or weather can account for blood sugar issues. So check frequently!
I'd call the hotel and see what they offer for fresh food. Many places also offer a grocery delivery service so you can stock up on things.
****is right! You'll be pros in no time. Try (ha!) to relax and enjoy!
