Airport security is stressful enough without standing in the TSA line wondering whether they're about to make you throw away your baby's bottle.
The good news: TSA makes several exceptions to the standard liquid rules when you're traveling with a baby. You can bring formula, breast milk, baby food, water for your baby, and other essentials through airport security — including quantities larger than the usual 3.4-ounce liquid limit.
Here's what you need to know before heading to the airport. If you’re planning your first flight, I also put together everything I wish I’d known before traveling with a baby.
TSA Rules for Traveling with a Baby: Formula and Breast Milk
Yes. Formula is allowed through TSA in quantities greater than 3.4 ounces.
TSA considers formula a medically necessary liquid, so it does not have to follow the standard 3-1-1 liquids rule.
You can bring:
Prepared formula
Powdered formula
Ready-to-feed formula
Bottles containing formula
You should tell the TSA officer that you're traveling with formula at the beginning of the screening process. TSA may need to screen the formula separately.
Mom 411 Tip: Keep your bottles and formula somewhere easy to reach in your diaper bag rather than buried underneath everything else. You'll likely need to remove them for screening.
Can You Bring Water Through TSA for a Baby?
Yes. You can bring water through TSA when you're traveling with a baby.
Water for babies and toddlers is allowed in reasonable quantities and can exceed the standard 3.4-ounce liquid limit.
This can be especially helpful if you're traveling with powdered formula and need water to prepare bottles during your trip.
Let the TSA officer know you're carrying water for your baby when you reach the security checkpoint.
Can You Bring Breast Milk Through TSA?
Yes. Breast milk is allowed through TSA in quantities greater than 3.4 ounces.
Even better: you do not need to be traveling with your baby to bring breast milk through airport security.
Let the TSA officer know you're carrying breast milk before the screening process begins. The containers may need to undergo additional screening.
Can You Bring Ice Packs Through TSA for Breast Milk or Formula?
Yes. TSA allows cooling accessories needed to keep breast milk, formula and other baby items cold.
These can include:
Ice packs
Freezer packs
Frozen gel packs
Other cooling accessories
These items are allowed even if they are partially frozen or slushy when you reach security.
Can You Bring Baby Food and Pouches Through TSA?
Yes. Baby and toddler food is allowed through TSA in reasonable quantities.
This includes things like:
Baby food jars
Puree pouches
Yogurt
Toddler drinks
Other baby and toddler foods
These items can exceed 3.4 ounces and do not need to fit inside your quart-sized liquids bag.
Tell the TSA officer that you're carrying baby or toddler food and remove it from your carry-on bag for separate screening.
Do You Have to Take Formula and Baby Food Out of Your Diaper Bag?
Plan on it.
TSA asks travelers to inform the officer at the beginning of the screening process when they're carrying formula, breast milk, toddler drinks or baby food in quantities greater than 3.4 ounces.
You'll generally want to remove these items from your carry-on or diaper bag so they can be screened separately.
This is one reason I recommend keeping all of your feeding essentials together and easily accessible when packing your diaper bag.
Can You Bring a Stroller Through TSA?
Yes. Strollers are allowed through airport security.
Your stroller will need to be screened. Depending on its size, it may go through the X-ray machine or be screened separately by a TSA officer.
What happens to your stroller after security depends on your airline and how you plan to travel with it. Many parents choose to use their stroller throughout the airport and gate-check it before boarding.
Always check your specific airline's stroller policy before flying.
Can You Bring a Car Seat Through TSA?
Yes. Car seats are allowed through TSA.
Like strollers, car seats will need to be screened at the security checkpoint.
Whether you check your car seat or bring it onto the plane is a separate question from TSA rules and depends on your airline, your ticket and the specific car seat.
If you're planning to use a car seat on the plane, check that it is approved for aircraft use and review your airline's policies before your trip.
Can You Wear Your Baby Through TSA?
Baby carriers and wraps are allowed through TSA.
You may be able to wear your baby through the security checkpoint, although TSA officers may require additional screening.
Even if you plan to baby wear through the airport, keep in mind that procedures can vary depending on the circumstances at the checkpoint.
Can You Bring Baby Medication Through TSA?
Yes. Medication for your baby can be brought through airport security.
TSA recommends that medications be clearly labeled to help facilitate the screening process, but TSA does not require medication to be in its original prescription packaging.
Liquid medications can also be exempt from the standard 3.4-ounce liquid limit when medically necessary.
Tell the TSA officer about medically necessary liquids at the beginning of the screening process.
What Else Can You Bring Through TSA for a Baby?
Most of the everyday items you keep in your diaper bag are fine to bring through security, including:
Diapers
Baby wipes
Pacifiers
Bottles
Blankets
Burp cloths
Toys
Extra clothing
Baby carriers
There isn't a special TSA limit on how many diapers or wipes you can pack, but your airline's carry-on and baggage rules still apply.
Tips for Getting Through TSA With a Baby
A little organization can make airport security much easier.
Keep liquids together. Put bottles, formula, water, breast milk and baby food somewhere you can quickly access them.
Tell the TSA officer you're traveling with baby liquids. Do this before your bags begin the screening process.
Give yourself extra time. Baby items can require additional screening, so don't assume security will take the same amount of time it did before kids.
Check your airline's policies, too. TSA determines what can go through airport security. Your airline determines things like baggage allowances and many stroller and car-seat procedures.
Check TSA's website before your flight. Rules and procedures can change, so it's always worth checking the latest official guidance before traveling.

The Bottom Line
Flying with a baby involves enough stuff without having to worry about whether TSA is going to take something you actually need.
The biggest thing to remember is that formula, breast milk, water for babies, baby food and toddler drinks are generally exempt from TSA's standard 3.4-ounce liquid limit when brought in reasonable quantities.
Keep those items easily accessible, tell the TSA officer about them when you reach security and leave yourself a little extra time for screening.
And always double-check the latest TSA and airline policies before your flight — because the last place you want to be figuring this out is in the security line with a hungry baby.
