Travels with Baby Tip #12: Remember to 3-1-1 Your Baby’s Travel Kit for Carry-On

Be sure to follow the TSA’s guidelines for any diapering and medicinal goodies you’ll want for your child onboard the aircraft: 3 ounces or less of each product, all stowed in a one-quart zip-top bag. The allowance is per passenger, so you can keep your own items in your own zip-top bag as well, or combine for simplicity if it all fits in one. Here is a sample modified “travel kit” for your child’s carry-on, with some items you may like to have onboard, especially for longer flights:

Sample modified travel kit for carry-on with 3 oz. liquid restrictions:

Infant’s Tylenol, 1 fl. oz.
Infant’s gas relief drops, 1 fl. oz.
Small tube of diaper crème, 2 oz.
Small tube of teething gel, .33 oz.
Tube of healing crème (sample from doctor’s office), .25 oz.
Saline nasal spray, 1.5 fl. oz.

Be sure to present your zip-top bags at security, placing them in clear view in your bins. For any questions about the TSA guidelines and the latest on what’s permitted, visit

    Thanks, Shelly! I've been getting such inconsistent info on a range of baby things — from airline to airline and customer rep to customer rep. It's quite frustrating. Your travel tips are great. Really appreciate it.

    Wow! That's interesting to hear – I just spoke with United and verified you were given incorrect info, so I hope this comment finds you! (Unticketed passengers are generally not given a baggage allowance, other than a diaper bag, so perhaps that was the source of confusion?) In my experience I have MANY times presented my ziploc right along side of my childs at the TSA screening. However, in more recent trips I have tried to simplify by combining my few goodies (travel-size toothpaste, eye drops) in the same bag with my lap child's carry-on travel kit. What may be more useful for you, however, is to pack one 3-1-1 zip loc with small items (similar to the above) and a second LARGE zip top bag to present in which you put all those additional, larger liquids you might need just for your child, including any milk boxes or prepared / breastmilk bottles, baby foods, or juice / milk boxes. These are also permitted for any baby or toddler, whether flying in a paid seat or on a lap. Please see the guide books for more details and tips.

    This is a great tip, but should be noted that an additional 3-1-1 is not permitted for a lap infant — or at least that's what United tells me. According to them, a 3-1-1 is only permitted for passengers occupying a seat.
