I have a 2010 Grand Caravan, so, same third row.
I think you are going to need either a bubblebum for your seven year old third row center and then maybe a maestro for the new 3 year old, with either the baby in infant seat or maybe, maybe the GN also in the third row.
Or, put a three year old in a RSTV third row center.
It's just so narrow back there :/
Have you tried the blvd70 back there yet? I thought our old classic blvd (now expired) did not fit well back there RF. I mean, it could be installed and be safe, but it just seemed to not puzzle well with the general shape of that third row seating area for trying to maximize space. But maybe the new style is better for puzzling??? Hopefully?
I have never achieved a three across back there except for one kid in a parkway and two skinny adults, and it wasn't too comfy for them.
I do have "tight three across" experience in our Prius, but haven't tried as hard to fit three carseats across in the van.
