Yes, you can absolutely take 200ml of baby milk through airport security in 2026, as baby milk, formula, and sterilized water are classified as "essential medical or dietary liquids." This means they are exempt from the standard 100ml liquid restriction found in most global airports. Whether you are traveling through the US (TSA), the UK, or the EU, you are permitted to carry a "reasonable amount" for your journey, which can easily exceed the usual limits. You do not need to fit these bottles into a small clear plastic bag; however, you must declare them to the security officers for separate screening. In many modern 2026 terminals equipped with 3D CT scanners, you may not even need to remove the bottles from your bag, but in older terminals, the staff may perform a quick chemical test on the liquid. A vital rule to remember is that in most regions (except for expressed breast milk in the UK/US), the baby must be present for the exemption to apply to formula or cow's milk. If you are traveling with breast milk without the baby, you are still permitted to carry it in larger containers, but be prepared for a more detailed inspection.
