My mom just bought our family a new car, she thought the screaming baby was making me nuts (she was right ). So now everyone fits comfortably (no one is crowding Miss Ellie), but I have a new problem. DD1's hbb is making it very difficult for me to see out the back window (she is in the third row driver's side seat). She will be 6 next month and is 65ish lbs and 49" tall. Would you feel comfortable with her in a nbb? She does still sleep in the car regularly, but sits very well in her seat otherwise. Any other options??? The car in an '06 trailblazer.
