how old are your kids? Are they in car seats?
We just had our third, so in a similar situation that required a bigger people mover. The oldest is in a booster seat, two youngest are in car seats. For us, a mini-van was the only option because it allowed easy access to the third row seating, even with the car seats in place.
We looked at SUVs with 3rd row seating. Tried to fit the car seats in the middle row - did not find any vehicle that allowed the 2nd row to slide forward enough (w/ a car seat in place) for a 5 year old to squeeze into the back row. Caveat - we were only looking at used vehicles that were couple years old.
There are a few new model SUVs that have 2nd row captain seats that allow better access to the back row. If you have kids with car seats, this is the only practical alternative to a mini-van
here is a list of SUVs that have 2nd row captains chairs:
