Evenflo big kid flips up, but the turbo is a better seat IMO. Did you try it next to the MA? probably a bit easier.
I haven't but the next time I try it out in the car, I can try that. I want her to be in the driver's outboard seat when she is in a booster because that way, she wouldn't be able to unbuckle the other car seats accidentally. So I'll have to move the RA50 to the middle (or I could try it with a RN RFing in the middle if that would be different than the RN FFing).
I had planned to get a Parkway SG for her when she's in a booster full time because I've heard that it's pretty narrow and the SG feature sounds nice and a little reassuring to me since Hannah is tiny. Now that I've tried a booster and realize what a pain it is, I want to try out the ones that don't have arm rests or that have flip up arm rests and see if those work better. I don't think I'll be ready to buy something new until around the spring.
I definitely want to have the Turbo Booster just be a spare. I can forsee her needing to be picked up from school by someone else from time to time and we do have the FPSVD but I think it would be easier to use the Turbo, especially if she is riding with a friend who already uses a booster. The FPSVD is in dh's truck anyway, I like to keep it there and installed so one of the girls can ride somewhere w/ him (we're getting the tether anchor put in soon, the dealership has the part, we just need to make an appointment).
I still like the looks of the Parkway SG but will go with whatever will be easiest to buckle. We might just keep using the RN until we can get a van though.
