Wow I'm sorry that you guys can't even get out in the car, luckily Kallie deals with the South Alabama heat really well, we can't spend long periods of time outside but the boiling hot car doesn't bother her.
Is she in to art projects? Maybe you could do that, take an extra bath? Read lots of books! Maybe go to the library and hang out there for most of the day reading?!
