I'm installing a convertible car seat for the first time, it is the Graco Contender 65. I'm installing it in a 2011 chevy impala. I've been reading through the manual and maybe I'm just overlooking, but can I or should I use the seatbelt and the latches both, or just one or the other?? Also it comes with an insert that goes under the baby, do I leave that in there regardless or are there certain rules on it?? My baby is 6 months old, about 20 lbs and 27 inches long.
Thanks!!
Thanks!!
