Security is the trickiest, riskiest and most stressful part of the entire trip, but with enough practice, it’s easy to look like a superstar while doing it.
Do yourself a favor and sign up for TSA-pre. The lines are shorter and you don’t have to take off your shoes. Trust me, taking off and putting on your shoes while juggling a stroller, baby and carry-ons is a feat where something will always go wrong. Also, DO NOT GET IN LINE AT SECURITY WITHOUT YOUR BOARDING PASS AND BABY BOARDING PASS. Yes, babies need their very own boarding pass too, so don't get to the front of the line and realize you don't have one. Trust us...we made this mistake once and it will never happen again.
You are allowed to bring breast milk through security. Tell them before you go through so they know they can check it if they need to. You are also allowed to bring water if it's for the baby. If you mention that the water is for you, you will have to toss it. So remember, all liquids are for the baby (safe to say this strategy won’t work with soda). However, gels and lotions need to be under 3 oz. So purchase some travel containers prior to the trip. Otherwise you will be leaving some precious baby aids behind.
If you are traveling with your partner, simply task one person with the job of holding the baby, and the other to do everything else. Plan this before you get there. This division of labor minimizes the chance you will forget something as you put items on the belt and gather them on the other side. Stick to this routine every time and you won't even flinch.
If you're traveling solo, ask for help. It is simply too much to fold your stroller, lift your carry-on and hold your baby all at the same time. The TSA is there to help. If they seem to ignore your requests, hold up the line and insist that they do. It is in their job description to help you.
Make sure to put your infant’s blanket in the diaper bag during this time so that it doesn’t fall out of the stroller or touch that nasty belt as you put it through the xray machine. In our case, we use wife's Zara pashmina as blanket so it can double as a cover-up as well to nurse.
Put wallet, phone and all pocket items in one place - a purse or a stroller zip compartment. With so many balls in the air, it’s easy to forget something if you do not consolidate.
Do not rush on the other side of security. Gather all your things and take a mental inventory of everything that you brought with you.
