How do you carry milk on a toddler on a plane?

Formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) in quantities greater than 3.4 ounces or 100 milliliters are allowed in carry-on baggage and do not need to fit within a quart-sized bag.



In 2026, TSA and international security agencies classify milk, formula, and juice for toddlers as "medically necessary liquids." This means you are allowed to carry quantities greater than 3.4 ounces (100ml) in your carry-on luggage. You do not need to fit these containers into a quart-sized bag, but you must declare them to the TSA officer at the start of the screening process. It is recommended to carry the milk in clear, translucent bottles to speed up the testing process, which may involve a Bottle Liquid Scanner or a vapor test. You can also carry ice packs or gel packs to keep the milk cold; these are also exempt from the liquid rules as long as they are being used for the milk. Note that the child does not necessarily need to be present if you are transporting expressed milk, but they usually must be present for toddler-specific drinks.
