If traveling by air, keeping your child in her seat can be a job unto itself. While bringing a car seat onto the plane is the safest way to travel, the seat itself is often heavy and cumbersome, not to mention it places kids' feet in the perfect position for kicking the seat in front of them. The CARES Fly Safe Strap ($75) has been approved by the FAA as a safe alternative for flying tots. It quickly attaches over the seat and to the plane's lap belt for a lightweight and easy way to keep kids flying safely.
