We are traveling out of town for Memorial weekend. It's our 1st trip since ds was dx'd almost 8 months ago. It's only about a 4 hour drive. I was going to put some extra insulin in our ice chest as we traveled but am now worried it might get too cold. We have been using the flex pens to fill the pump res. I have one that's already opened that will be in his d bag, but I am bringing an extra as a "just in case." What would be the best way to store insulin while traveling? Also, we are planning a hike while gone. Ds has been on the pump for about 6 weeks and it's only been while on the pump that we notice how much exercise affects him. Should I do a temp basal during the hike? (Never done a temp basal before ) Not sure how long we will be gone or the pace at which we will be hiking. Are there any snacks that would better help maintain his numbers? Normally he would just have half of a granola bar for p.e. Any info would be greatly appreciated. I just want to go into this mini-vacation feeling as prepared as possible! Thanks so much.
