You have gotten good advice on this thread. The main thing is to make whatever you have easily visible to the TSA when going through the security line. We try to unload it all while we're waiting in line and put it in a separate bin (blue ice packs, zinc ointment, vaseline, drinks, yogurt, cottage cheese, and other food). We rarely run into any problems. When we have, we have asked for a supervisor and it has always turned out okay. If you do encounter some initial resistance, just remain calm and ask for a supervisor. My wife always carries our daughter, who is currently two, through the metal detector. We have never been questioned on that.

I hope you have a great trip.
