My 6yo is going on a field trip and they asked for parent drivers. Being a car seat ummmm......nut, I don't want my dd riding in some else's car in who knows what or nothing. So of course I volunteered to drive and take a few kids with me. I have a 1994 Suburban and here's my plan. Third row-2 Regents outboard tethered (the only tethering options in the car). Second row-Nauti behind driver, RadianXT in center, and Monterey on the sliding seat. I haven't actually checked yet, but I'm pretty sure I'll still be able to slide the seat forward with the Radian ff there. It's rf right now. I also thought I might pick up a couple of Harmony backless boosters at Walmart this weekend, just in case there are kids who need to borrow them and they would be nice just to have around for emergency purposes. Sound like a good plan?
