When my daughter was a toddler, she could escape my clutches in a flash and run away, sometimes almost running into the street! I bought a cute puppy backpack-style child leash so I could safely keep her with me.
I had no idea a child leash was such a controversial item! I got many dirty looks and several nasty comments when using it. For the record, my daughter didn't mind it at all, and it worked great for us!
