I appreciate all the help so far. Need to figure out car #2. I just realized that my pudgy baby #3 will likely hit the RF weight limit of the 2012 boulevard before we want to turn him FF (ideally after age 3.5). My new plan is to keep DC #2 in Blvd FF. The seat expires in 2018. At that point, DC#2 should be fine in a booster. Dc#1 is in a low back booster.
So I will need a new convertible seat for DC#3 that will let him RF til 40lbs+ and can fit 3 across in an Odyssey. My head is spinning! Thanks for the help!!!
