We are traveling next week and need two car seats once we get there. I really don't want to bring two giant car seats so I was thinking about just bringing one car seat ( britax) for our three yr old and then bringing the booster part of the nautilus for my 4.5 year old who is 40 lbs. Has anyone used the nautilus as a backless booster for a 4 yr old ?
Re: Graco nautilus booster
I still use the 5-point harness on my almost 5yo with our Graco Nautilus. I'd read through the directions that came with it if you are dead set on using just the booster. However, I think you should definitely consider bringing what you and your child are accustomed to using. Is your child used to riding in a booster without a back? I'd be hesitant to switch for fear of having issues keeping my child in the seat while traveling. For me, switching just before traveling/during travel would be a recipe for disaster.
I've heard good things about the Cosco carseats for light, cheap travel carseats. But for our travel needs I didn't feel comfortable using anything but DS's (3yo) carseat - we checked it with the luggage. For the plane ride we used the CARES plane harness - it fit in my carry on.
Why don't you want to bring the carseats if I may ask?
