It can be helpful to have your child participate in selecting the harness. Limit the choices to two or three you think will work well for you and your child and then have them pick their favorite. Let your child open the package and try on the harness in your home. Explain the situations where the harness will be used. Avoid talking about the scary things that can happen and instead explain that they will be able to walk around without holding your hand while staying close by and safe. Ensure that the harness isn’t too tight and is comfortable to wear.
