We carried on all supplies without incident. No one even looked at our insulin, cold packs, needles, etc. Ds7 even walked through the machine without incident here in Dallas while wearing his pump.
However, on our return trip out of San Diego, after REPEATEDLY telling EVERY SINGLE security person that ds7 was wearing an insulin pump, the pump caused the machine to alarm and we were surrounded (no joking) by security personnel and told that ds would have to be taken to a secure room to be searched!

He was terrified. I was terrified. I asked reapeatedly if we could remove the pump and have him walk through the machine again and was told that they could not ask us to remove the pump. My son was terrified and crying, there were five or six guards around him, scaring him half to death, he was crying for me, they were yelling at me to not touch him. My other three kids were scared to death. Finally, I told them that they were not taking him to a room--he could be searched right there in front of everyone in the airport. They gave him a half-a$$ed pat down--never even looked at his pump (which could have easily been a gun for all they knew) and sent us on our way. They scared my child half to death just for show.
Anyway, I know this went waaayyyy off topic, but I try to let people know about how dumb some of these "trained professionals" can act just so others don't have the same thing happen to them.
