The House passed a bill Tuesday to codify existing Transportation Security Administration rules allowing breast milk, bottles and other nursing-related items through airport security and onto planes, after reports that TSA isn’t following its own guidance.

Lawmakers passed the Bottles and Breastfeeding Equipment Screening Act, or the BABES Act, in an easy voice vote Tuesday afternoon. Rep. Jaime Herrera-Beutler, R-Wash., said she introduced the bill because it’s clear TSA screeners don’t always understand that the agencies rules allow these items to pass through security.
