We're planning a road trip for late December. I have four kids and three of them will be able to ride fully harnessed (in a RA55, RN100 and GN), therefore "safe" if we choose to drive at night. However, DS1 is 11 and way too big even for a booster seat (boosters make him too high to fit the shoulder belt properly). Is there anyway to drive so that he is safely "belted"? I drive a Honda Odyssey. I thought maybe I could put him in a captain's chair that I recline or more than slightly?
TIA!
