My mom put 5 year old me and my 3 year old sis on leashes. Of course, we were on a Navy ship heading for Japan where my dad was stationed.
My mother put a leash on me and snapped the other end on the clothesline.
Explains a lot!!!
While we never did it, having experienced the terror of thinking you’ve lost a child would be enough to make me think about it. (Of course my kids are all grown men now, but I do have a grand daughter)
