Right! I flew with my toddler recently and had liquids (milk) in excess of 3oz to feed her with. Totally permissible by TSA, I looked up all the rules before packing.

At Richmond, multiple TSA officers were questioning my reasons for having milk and lecturing me about how I should have put the milk in a clear bottle because otherwise it “takes extra time” (turned out to be a 30 second affair). When I flew home from Puerto Rico I got not of the attitude whatsoever.
