Wow you all, those tips are awesome! Thank you so much! My list is already so long it's ridiculous! I didn't think about bringing those food items, but it makes sense.
A question for Suzyljank--where do you get an epi bottle? And what are the Therma care back wraps--does this take the place of a heating pad?
Today, I ordered an inflatable seat for the flight. Even though it's not more than four hours (unless we can't take off, which is happening these days!) I have very limited tolerance for sitting. It is a major factor in my last re-tear!
Owmybum, I hope you're right and that I'll be able to enjoy myself for most of the time!
I hope others will benefit from these great ideas as well!
