Yes, you are absolutely allowed to take baby food through airport security, and it is officially exempt from the standard "3-1-1" liquids rule that applies to most passengers. According to TSA and international aviation standards in 2026, baby food, breast milk, toddler drinks, and distilled water for formula are considered "medically necessary liquids." This means you can carry them in containers larger than 3.4 ounces (100ml) as long as they are in "reasonable quantities" for your journey. When you reach the security checkpoint, you must notify the officer that you have these items and remove them from your carry-on bag for separate screening. Officers may use specialized equipment to test the liquids, or they may ask you to open a container for visual inspection. It is important to note that the child does not always need to be present if you are transporting breast milk, but for baby food and juice, having the child with you simplifies the process. To ensure a smooth experience, pack these items in a clear bag and be prepared for a slightly longer screening process than a standard traveler.
