This issue could be easily resolved if every afternoon parents just brought their children to a fenced-in Child Park where they got to run around for a few hours. It works for dogs.
Plus then communities can restrict play to only vaccinated children. The anti-vax parents and their unvaccinated children can start their own play group or something.
Of course I am not serious. Some children run around grocery stores. Yet they are too old to be restrained in a shopping cart.
Even if the child is on a leash, he or she may still end up turning the corner too fast.
No one wants his or her child dashing into oncoming shopping cart traffic. For these moments, maybe a retractable leash works best?
