My little one was recently diagnosed with a growth hormone deficiency and this will be our first time traveling with medication that needs refrigeration. She uses Humatrope and we were sent a travel bag. However the bag says the meds can stay in there 5 hours. I'm worried now because our flight alone is almost 3 hours!! Can anyone offer some advice on the best way to carry and keep the meds cool? I'm probably stressing out about this more than I should be but this is all really new to me. Thanks so much in advance.
