Ever wonder what that funny looking strap and plastic piece are that comes with your booster? It is called a shoulder belt positioning clip and is used to keep the shoulder belt at the correct position when using a backless booster. The fabric loop attaches to the bottom of the booster and the red clip attaches to the shoulder belt above the shoulder. Make sure to read your car seat manual to find out exactly where to attach it and when to use it!
