Acceptable Use Of Child Leash

I'm aware that earlier I said that child leashes are inhuman and should never be placed on a child.  I stand by that statement completely but I know that some people will still continue with the use of child leashes ( The correct term for this is child safety harness but I feel that by saying child leashes there is a deep negative connotation with the word leash that will further illustrate my points).  Knowing that some people will still use child leashes I feel that those who decide to use them should only do so as a last resort, not an initial practice.  If your child is acting up and don't respond with you telling them to cut it out then you should put them on the leash.  That I believe will stop the child from acting up than just putting them on a leash every time they go out to a public setting.
