With child #3 on the way, we've come to the conclusion that its minivan time! We're currently between a 2012 Odyssey vs a 2012 Sienna, and I'm trying to figure out which will work best for our carseat configuration. When this baby arrives, we'll have her in an infant seat, our 2-year-old in a RF Boulevard (latch) and my 4-year-old FF in a Radian (seatbelt install). My 4-year-old is small, so a booster is a while off. What are some of the pluses and minuses of three car seats in these two minivans? I'm in a urban area, so there's plenty of parallel parking on busier streets, so anything that makes loading and unloading children easier is very much preferred. Thanks!!!
