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.
Although not required, to expedite the screening process, it is recommended that formula and breast milk be transported in clear, translucent bottles and not plastic bags or pouches. Liquids in plastic bags or pouches may not be able to be screened by Bottle Liquid Scanners, and you may be asked to open them (if feasible) for alternate screening such as Explosive Trace Detection and Vapor Analysis for the presence of liquid explosives. Screening will never include placing anything into the medically necessary liquid.
TSA X-ray machines do not adversely affect food or medicines. However, if you do not want the formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) to be X-rayed or opened, please inform the TSA officer. Additional steps will be taken to clear the liquid and you or the traveling guardian will undergo additional screening procedures, to include Advanced Imaging Technology screening and additional/enhanced screening of other carry-on property.
Ice packs, freezer packs, frozen gel packs and other accessories required to cool formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) – regardless of the presence of breast milk – are also allowed in carry-ons, along with liquid-filled teethers. If these items are partially frozen or slushy, they are subject to the same screening as described above.
