Can You Bring Liquids for Baby on a Plane?
Parents traveling with infants are frequently confused by airport security liquid limits. The TSA, CATSA, and international civil aviation authorities have specific medical exemptions that permit baby liquids well above the standard 3.4-ounce (100 ml) travel limit.
Updated August 2026
Quick answer
Yes, you can bring baby liquids on an airplane. The TSA officially exempts formula, breast milk, toddler drinks, liquid baby food, and puree pouches from the 3-1-1 rule (3.4 oz / 100 ml cap). You are allowed to carry reasonable quantities required for your travel duration in your carry-on baggage. Gel ice packs and freezer packs are also permitted to keep them cool.

Rules for bringing baby liquids through airport security
- •TSA classifies breast milk, baby formula, distilled water for mixing, toddler juices, and puree pouches as "Medically Necessary Liquids". They do NOT need to fit into a quart-sized plastic bag.
- •You are allowed to bring liquid containers larger than 3.4 ounces (100 ml). A standard 8 oz bottle of prepared formula or a 6 oz pouch of organic baby food puree is fully permitted.
- •Ice packs, freezer packs, and frozen gel packs are allowed to keep baby milk and food cold. Keep them as frozen as possible when passing through security to reduce screening time.
- •Declare your baby liquids to the TSA officer at the start of screening. Place all bottles, milk bags, and food pouches into a separate plastic bin so they don't trigger a full bag search.
- •TSA screening methods: Officers typically inspect bottles by eye, swab the exterior of containers for explosive traces, or hold unopened bottles over an electromagnetic liquid bottle scanner (BLS). They should never touch the liquid inside.
- •Bottled water for baby formula: You can bring pre-filled bottles of sterile or nursery water through security. Let the officer know it is for formula preparation.
Common mistakes when traveling with baby liquids
- •Packing baby milk or formula in checked luggage. Flight delays or lost luggage can leave your baby without food.
- •Letting melted, warm ice packs float in your bag. Liquid ice packs without milk or baby food may be confiscated; pack them alongside your baby food.
- •Trying to hide bottles in deep backpack pockets instead of placing them in a separate screening bin.
- •Traveling internationally without checking foreign transit rules: while the US and Canada allow baby water, some European and Asian airports require the infant to be physically present at the checkpoint.
FAQ
Can I bring liquid baby food pouches through TSA?
Yes. Commercial and homemade baby food puree pouches (even 4 oz or 6 oz) are permitted through airport security in your carry-on.
Can I bring water through security to mix baby formula?
Yes. TSA permits bottled water, nursery water, or pre-filled baby bottles of clean water specifically intended for mixing infant formula.
Do I have to open the formula bottles for TSA?
Usually no. TSA uses bottle scanners that test through plastic and glass. In rare cases where a bottle cannot be scanned, officers may ask you to open the container for a vapor test strip.
