Juggling luggage, a toddler, and a car seat when you travel? Lighten your load with an extra set of wheels! Made to easily attach to most car seats, it lets you navigate the airport with ease. Instead of carrying your car seat, you can roll it right along with you, and it's even sturdy enough for your baby to ride along in style. The FAA recommends that children under 40 pounds sit in a car seat while flying, so don't skip the car seat, but do skip the extra effort!
