Outback with 3 kids under 6?

So - we bought a 2023 outback with the expectation of having 2 kids total. Life had other plans though and baby 3 is on the way.

Has anyone used their outback with 3 young kids? The oldest will be 5.5 by the time the baby is born and would be big enough to be in a booster seat. Is squeezing a car seat in the middle possible?

Really, really hoping we don’t need to get a bigger car. Has anyone here made it work with 2 in a car seat plus a booster seat?
