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. Formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) are considered medically necessary liquids. This also applies to breast milk and formula cooling accessories, such as ice packs, freezer packs, and gel packs (regardless of presence of breast milk). Your child or infant does not need to be present or traveling with you to bring breast milk, formula and/or related supplies.
Inform the TSA officer at the beginning of the screening process that you are carrying formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) in excess of 3.4 ounces. Remove these items from your carry-on bag to be screened separately from your other belongings. TSA officers may need to test the liquids for explosives or concealed prohibited items.
