Hello I have the 8 passenger seating in my traverse and have 2 year old twins. I want to be able to use the back seat so im thinking of putting the car seats next to each other in the second row one behind the driver and one in the middle,has anyone else tried this?My other option would be to put one seat in the third row but Im not to sure how to position it. The middle seams logical as it has a top tether anchor but the seat belt on the headliner confuses me on hooking it to my car seats or do I use one of the side seat belts? Any advice would be greatly appreciated as Im trying to get the most out of this vehicle
