Hey all! I do believe my soon to be toddler will be the type to run off in public (once they open it back up that is)

What is the best book bag or whatever devise you’ve used to help a child not wonder off?

*Please don’t make rude comments about leashing your child. As a nanny I had to save a child (not even the kids I was watching) from danger. One was almost hit by a car! Scared the crap outa everyone. I trust my lightening fast reflexes, but I’d rather not yank another kid back by their hoodie, ya know?
