To tighten your harness, you will pull on the harness adjustment strap to tighten your harness snugly. Grasp the harness straps just above the crotch buckle and pull up to ensure the lower part of the harness is snug.
Position the chest clip at armpit level (mid-chest and away from child’s neck).
Check harness tightness by pinching the harness at the shoulders and hips. Pinch the harness vertically between index finger and thumb as shown.
If your fingers slip off, the harness is tight enough. If you can pinch the harness strap, tighten more. The harness straps should be snug throughout their length.
A snug strap should not allow any slack. It lies in a relatively straight line without sagging. It does not press on the child’s flesh or push the child’s body into an unnatural position.
