Here are a few photos of some accessories we saw that might interest you, especially with fall and winter around the corner. Neither of these interferes with the harness system or carseat padding in any way, so you can use them safely!
First, the Carseat Blankie is a very nice baby warmer; it’s a right sized flannel blanket available in various patterns. It can travel with baby in the car or around the house.
Next, the BabbaCo infant carrier covers, in a wide range of cute designs for both winter and summer!
