My oldest is about to turn 10. She's a tall girl, mature, about 67 pounds, and will sit correctly in a seat belt. She's currently in a high back Parkway SGL. I took these photos in the driveway so I could ask you guys what you think. Do you think she's ready to come out of the booster? If she meets all the criteria for safely sitting in a regular seat, is there any added safety to keeping her in the Parkway? I'm in no rush to move her....just noticed she's getting tall in that Parkway (but hasn't outgrown it yet).
