We're expecting our third child this September. At that time, DD1 will be 4y9m, and DD2 will 2y9m.
We are in a 1995 Ford Explorer, with no third row. A new vehicle is not an option and won't be for quite a few years.
Currently, DD1 is in a Britax Frontier 85, harnessed. (This is behind the drivers side. I can't put a RFer behind my DH because it either a) pushes the seat up too far for him, or b) pokes over the top of his headrest which is not moveable and would hurt him in an accident.
DD2 is in a Sunshine Kids Radian XTSL (rear facing, intend to keep her this way!). She is RFing center.
There is no room for another car seat. I've tried a MyRide (because the base is small and the top overhangs) and a few narrow infant seats. Not center, not outboard. They just don't fit.
My DD1 is a tall girl. She has outgrown the Radian both rear facing (by weight) and forward facing (by torso height).
I'm not concerned with her being able to buckle the booster herself- I have smallish hands and can do it for her, or we can just leave it buckled and have her scoot up under the belt to get in the seat.
The Frontier85 has an external width of 19". A Turbobooster is 16". That would allow me three more inches to get an infant seat or another radian in there. Your thoughts?
