"Turn your head for a second and boom "where did they go"...
My first daughter was like that. We took care of it very soon. Back then they had what was called a child's leash. It was great. Now you would more than likely be accused of child abuse if you used one.
There are images of me as a shaver on a child’s leash, with my mother holding on as the family, all bundled up, stood outside on the Eiffel Tower observation deck on a cold, blustery day. Dad not in the pictures; he was the photographer!
