TSA-approved breast milk coolers are a savior to the traveling mothers who wish to keep their milk fresh, safe and ready to feed as they travel in the air, whether you are a working mom on a business trip, or you are taking a family vacation.

We will discuss the selection of the most appropriate TSA-approved breast milk cooler, what to include, and some of the professional tips that will enable one to carry pumped milk and travel with it without fear or trepidation.

Understanding TSA Rules for Breast Milk and Coolers

When you are traveling with your baby or pumped milk, it is better to know the TSA regulations regarding breast milk and coolers to save a lot of stress at the airport. The Transportation Security Administration (TSA) permits parents to carry breast milk, formula and baby food in a reasonable amount via security despite them having more liquid that is above the 3.4-ounce limit. You do not even need to be on a journey with your baby to carry the breast milk, either; just tell the TSA officers that you have it.

During the screening, take out your TSA-approved breast milk cooler from your bag and inform officers that it has breast milk or ice packs. Although the cooler and the contents can be inspected as a security measure, TSA employees are supposed to handle breast milk with care and respect. Gel packs, ice packs and frozen milk are also allowed, provided that they are partially frozen or slushy.

These rules are easier to learn in advance, and then go through security without any hassles and with your milk at the correct temperature to give it to your baby.
