3 car seats, 1 suv??

Hello! My husband and i have (almost) one year old twins and we’re hoping to begin trying for a third within the next 12 months.

One of our largest “logistical” pieces of going from a family of four to five is our car / car seats. Right now, i have an Acura MDX but my husband will soon be in the market for a new car. My car does have 3 rows, but when the third row is up, there is little to no trunk space. I also think that it’ll be difficult to have 2 car seats + an infant seat in one row, or have to climb all the way back to the third row to get the boys in.

Those who have triplets or twins / singleton spaced within car seat years, what is your set up?
