Hi, I'm fairly new to the posting here but I've been reading the boards for several months and you ladies ROCK! I find I need some advice concerning a carseat for my 3yo for DH's car. Right now he's kissing the 40lb mark, but he's far too immature for a bpb so I need a combo seet with a harness. I've looked at the Graco Ultra Cargo and the Evenflow Chase. I've seen a Nania Airway online, but have not located it locally. Can someone steer me in the right direction? I feel like I'm spinning my wheels. Does anyone have any experience with the Nania Airway?
