13. Tighten the Harness by Pulling the
Harness Adjustment Strap
A snug harness 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.
When you are not able to pinch any of the
harness webbing at your child's shoulder,
the harness is tight enough.
