When I married, I inherited three boys ages 3, 4 and 5. The Toddler was a handful from the git-go, so leashing him was the only kind thing to do! Tying him to a cinder block in the yard also worked - he could run away, but at a very slow pace, LOL! (I’m certain I’d be arrested for that these days!)
We played, ‘Red Light, Green Light’ with the other two when we were at a Mall or at the Fair, or just out for a walk after supper with the dogs. That worked well, too. They were ALL trained to FREEZE IN PLACE when one of us yelled, ‘RED LIGHT!’

I hope you didn't play this version.
