We're expecting #3 in September and unfortunately our two cars are a Honda Element and a 2008 Honda Civic. Both are paid for, so I'm looking to avoid a car payment for as long as possible, although I know that eventually we'll be buying something bigger. My oldest is 4, 40" and 35 lbs, he's currently FF in a Marathon. My youngest is 1, 29", 20 lbs and is RF in a Britax Chaperone. Is it really possible to put 3 across in our Civic safely? I measured the back seat this morning, roughly 53" wide. Or will we be like sardines in a can and I should just give up and buy a van ASAP? Thanks for any suggestions or advice!
