Don't worry, I've seen that from plenty of "normal" people.
Seriously, when you have children, the first time he/she lunges into traffic, after the absolute horror goes away, a harness suddenly seems like a much better idea. And, after he learns his limits, to stay close to Mommy and Daddy in the parking lot and at the store, the harness can join his first shoes and snap-ups and the binky in the back of the closet. Keep the stroller close by, however. Toddlers poop out fast at the park.
I know some kids that need that...
I find leashes for kids hilarious!
(probably a good thing I’m not a parent)
