Get TSA PreCheck
If you don't already have TSA PreCheck, now's the time. Until your kid is 12, they can go with you through the lane, so it's a no-brainer for a parent, but it's even more important when you're flying with a baby. You don't have to take off your shoes or jacket, or take out your liquids or laptop from your carry-on, making life much easier. Depending on the airline, you may or may not need to take your baby out of the carrier; it's not that bad to take them off, but it's really a breeze when you don't have to.
