Security
By the TSA Wait Times team · Updated · Published June 2026
Flying with children adds a layer of gear — strollers, formula, car seats, juice boxes, tablets — that can turn a straightforward security lane into a stressful bottleneck. The good news: TSA has clear, parent-friendly rules for most of it. Know them before you arrive, and the checkpoint becomes the easiest part of the airport. Here is everything families need to know, from baby liquids at the X-ray belt to getting kids through the scanner without a meltdown.

TSA exempts formula, breast milk, toddler juice, and water used to mix formula from the standard 3.4-ounce / 100-ml 3-1-1 limit. There is no fixed maximum quantity — bring a reasonable amount for the length of your trip. Declare these liquids to the officer before you reach the X-ray belt and remove them from your bag for separate screening. TSA may run a vapor-residue or chemical test on the containers; agents are not permitted to insert anything into the liquid itself.
| Liquid type | 3-1-1 required? | Notes |
|---|---|---|
| Infant formula (powder or ready-to-feed) | No | Any quantity; declare at checkpoint |
| Breast milk | No | Any quantity; ice packs to keep it cold also exempt |
| Infant/toddler juice | No | Apple, pear, grape etc. — any container size |
| Water for mixing formula | No | Reasonable amount; may be tested |
| Adult water bottle | Yes | Must be empty or ≤3.4 oz to clear checkpoint |
| Adult beverages / sunscreen | Yes | Must be ≤3.4 oz in quart-sized bag |
Children 12 and under can keep their shoes, headwear, and light jackets on when walking through the standard metal detector — no exceptions or special lanes required. If a child is directed to the full-body scanner (AIT), light jackets must come off and go into a bin, but shoes still stay on. This rule is a stable TSA policy confirmed on the agency's Traveling with Children page and applies at every U.S. airport checkpoint. Adults still follow standard rules: shoes off, belts off, laptops and electronics out.
All strollers, car seats, booster seats, and blankets must be placed on the X-ray belt or undergo a physical pat-down — there are no exceptions. Fold your stroller completely before you approach the conveyor so you're not the bottleneck at the checkpoint. Gate-checking the stroller happens at the aircraft door after security, not at the security lane, so it still passes through X-ray on the way in. A soft carrier or baby wrap worn on your body goes through the metal detector with you and triggers a secondary hand-swab test on both you and your child.
Many large and mid-size airports designate family screening lanes — look for signs at the checkpoint entrance marked “Families” or “Special Needs.” These lanes are staffed by officers accustomed to extra gear and slower-moving groups. TSA PreCheck is the biggest single upgrade for traveling families: the lane is shorter, laptops and liquids stay in bags, and shoes stay on for everyone — kids 12 and under travel free under a parent's Known Traveler Number (KTN) with no separate membership required until age 13.

The best tactic for moving a family through the body scanner or metal detector without a scene is to send adults first so children see that walking through is uneventful. One adult proceeds through, turns around, and calls the child by name to walk toward them — this frames the scanner as a doorway, not an obstacle. If a child becomes distressed at any point, you can request a private screening room and TSA is required to provide one. Officers are trained in modified, child-appropriate screening procedures.
The single biggest time-waster at family security is digging for items that need to come out of bags. Pack baby liquids in the outer pocket or top-zip of your diaper bag so they can be pulled in one motion. Keep kids' tablets and portable gaming devices in their own mesh pouch since they require a dedicated bin in standard lanes (PreCheck exempts them). Solid snacks — crackers, fruit, granola bars — have no quantity restriction and need no bin.
One more common question at the checkpoint:
Ask any TSA officer for a private screening room at any point — the agency is required to provide one. You can also call TSA Cares (855-787-2227) up to 72 hours before your flight to arrange advance passenger support, especially helpful for children with disabilities or sensory needs.
