I pick up my 7 seat Model X tomorrow, we're very excited. We have 3 kids and 1 more arriving in November. They are 5, 4, and 2 years old. Once the baby arrives, we'll need a 4th (rear facing). My wife and I were thinking the new born (We have a Peg Preggo car seat) would go in the 2nd row passenger side. The remaining kids in their boosters (2 Dianos and 1 Graco) in the rest of the seats, leaving the middle seat of the 2nd row free for an adult to go back and attend to the baby if needed. We also got a 7 seater because the there's always a friend who comes along for whatever family outing is going to happen. What configuration do you guys recommend for the configuration?
