Carseat caboodle

Yes or no. I understand you don't add extra padding or anything in an infant carseat because it is in fact dangerous. But my infant carseat has no head piece. The way its looking is I might have a preemie baby. I was thinking about buying the carseat caboodle that has five pieces. The carseat wrap type thing, head piece, blanket and it comes with a carseat cover. I was just going to do the carseat cover for warmth and privacy because it'll be February and cold when she's born. What are you honest opinions. I'll add a picture of the carseat and of the caboodle.. The only reason my carseat will be without the head piece is because my friend was pregnant with twin girls until unexpedetly she lost one and had this carseat just sitting in storage. It is still in date and I know for a fact it hasn't been in a wreck, but somehow she lost the head piece.
