7-8 penger vehicle that can fit 3 toddler seats in the 2nd row?

I would like to lease a new vehicle that has the option for 7-8 pengers, but can fit three baby/toddler seats in the second row. The reason is because with baby #3 on the way, we would like to be able to have all three little ones within reach and keep the back seats down so we can lug big things around which we need to do often for our business (we homeschool so our kids are usually with us as we travel around to take care of the chain of local businesses we own). But then if we have a fourth child we still have the option of more seats. What models of wagons/vans have this option?
