Yes, you can, as long as they are frozen solid. Check tsa.gov for more info.
I agree that hard boiled eggs and cheese will be fine going a few hours without refrigeration, especially if you pack them in an insulated bag.
You can't bring ice packs through security.
True. I just copied this from the TSA site:
'Frozen items are allowed as long as they are frozen solid when presented for screening. If frozen items are partially melted, slushy, or have any liquid at the bottom of the container, they must meet 3-1-1 requirements.'
As a diabetic, I carry those solid blue ice frozen thingys through several times a year. I have a Victoza pen, needles, and a snack in with them in an insulated lunch bag. I do pull them out and put every thing in that insulated bag in their own bin though. They've never received a second look from TSA. I do have a list of my medications and diagnoses from my doctor, but have never been asked for them. Technically the Victoza pens do not have to be refrigerated once they are open, but I like to keep everything together, so put them in there.
If I was the OP, I'd get a note from my physcian stating that my son had to have protein snacks regularly due to his physical condition. She shouldn't need it, but would have it just in case.
Once again, yes you can. See the link in post #22.
Please check the tsa.gov website before posting erroneous information.
Post #22 contains a gotcha: the poster is diabetic, and she is using the blocks to cool medical supplies. That is a medical supply exception, and ice packs are always allowed for breast milk or for medications that need to be kept cool -- which is NOT the same thing as cooling regular food. Different rules apply.
disneyfaninaz . . . No sense trying to make sense of the senseless, Airport Security Screeners are totally inconsistant in applying the "frozen" rule.

OP's best bet is to use ice in a baggie, empty out the liquid before passing through security and hoping for the best. Worse case, get ice from one of the food places airside.
Actually, OP's best bet is to freeze either cheese sticks or tubes of Gogurt to be used as mini ice packs inside an insulated bag. No need to hunt down ice and/or a way of dispensing with the melted remains. Once the products thaw out, they can be consumed. If TSA has any issue with potentially partially thawed Gogurt, the tubes can easily be added to a 3-1-1 baggie and passed through security that way. No fuss, no mess, and things to snack on to boot!
