Car Seat Trouble

Well...the new car seat business is the pits.  I am not sure we are going to be able to get the seat to fit in our car correctly rear-facing to get the right angle. At this point,  with 3 pool noodles to lift up the front, we still have a floppy-headed sleeping baby. I drove today reaching into the back seat to hold his head up and then held the poor boy in my arms to finish his nap.  I think we need to find a solution to this problem quickly.
