Here's a little car seat travel hack for those heading flying with little kids soon! Snag a foldable trolley like this one off Amazon so you can ROLL your car seat(s) through the airport and onto the plane. On our most recent vacation, I stacked both of our light weight travel car seats (they're 7.8 lbs. each) on top of each other and used one trolley to pull - it worked like a charm. The key is aligning the bottom car seat right in the center of the trolley, then securing it tightly with one belt towards the bottom (thread through where the seat belt would go). Then you stack the other car seat on top and use another belt to secure (or the attached bungee cords if you buy the exact trolley we have that's linked). Our trolley came with 2 belts, too, FYI. Questions? Drop them in the comments! I know this can be a little confusing, but I'm here and happy to help. LTKWatchNow LTKTravel LTKKids
