Does anyone (Bart, anyone) know whether women travelling with a breast pump can carryon the empty, sterile/sealed containers to pump the milk into? The containers are 6oz size. They do not come in a 3oz or smaller size.

I'm a nursing mom with a 3 month old, travelling on business without the baby for 4-5 days. I will have to pump at least once during my overseas flight, probably twice. I need to carry on the containers. They are basically part of the pump apparatus. I must pump every 4 hours or risk mastitis - so for my own medical necessity, if stretched to explain.

I cannot find anything about carrying empty containers on the TSA site and my emails to TSA from a week ago are going unanswered.

(I've about given up on the idea of carrying my expressed milk on the plane, and will attempt to check it, frozen in a cooler, on the return flight. I've read and heard about many cases of moms having to dump expressed milk when going through security, I can't risk that.)
