I'm expecting my SLT-1 Silver/Ebony in a few weeks. We have 2 kids and I want to keep the car seats in the car most of the time. Where are people placing the car seats if you have 2? I purchased the Acadia planning to put them in the 3rd row, but pictures I've seen on this forum show a car seat in the second row. I will have captains chairs for the 2nd row. If I put them both in the second row, am I limiting access to the third? Any reason not to keep them in the 3rd row?
