I was recently traveling and was curious about traveling with breastmilk, or other baby food.
Formula, breastmilk, toddler drinks and baby/toddler food in amounts greater than 3.4 ounces or 100 ml ARE allowed in carry on bags and do not need to fit within a quart sized bag
this also applies to supplies needed to keep breastmilk cool – freezer packs, ice packs and gel packs are allowed regardless if you have breastmilk or your baby with you
easiest way to have smooth travels is to inform the TSA officer at the beginning of your screening process that you are carrying breastmilk (or formula to infant/toddler food) in amounts greater than 3.4 ounces
