What works best? If you do 3 across, who's in the middle? Where's the youngest? What are the ages?
If you have a minivan or suv, who's in the back? Is it a pain for them to get back there? Do they resent being the only one? Where is the baby?
We have a Pilot, and I can't imagine my eldest being happy by himself in the back (age 5). I can't imagine my 2 year old back there, either. Obviously, new baby won't go back there...But, with 3 across, I think they might kill each other. Eldest in the middle next to baby because 2 year old might hit baby while 5 year old can mostly be trusted? Oh, I get stuck on these simple logistics! Would it be easier in a minivan, or the same issues arise? On top of it, only the 5 year old can climb up into the very high vehicle by himself (another reason for eldest to be in the middle), so I will have to lift in the baby and the 2 year old for some time. Can only imagine bucket seat on the end. But why did I buy an 8-seater if we are going to scrunch into 2 rows anyway?
