Son is 13 months old, and he loves his binker (plug, binky, pacifier), and when he has it in, he won't try and eat anything. This gives me much peace of mind, that I can let him go off and do stuff. He can easily grab his binker, and take a bite of food, but he never does it when out and about.
Knowing he won't eat random crap, like rocks, makes it easier for me to let him run around in our back yard, and I let him run around the pool without one of us right next to him.
The pool thing seems crazy, but we tell him in a calm voice, no, danger if he gets too close, and if he does fall in, I'm seconds away of jumping in and getting him, so it's not a big deal.
As for the article, totally agree. It's crazy that despite the whole stranger danger thing, that abduction rates have stayed the same or gone down. Maybe that is cause and effect though. Stranger danger has prevented the abduction rates from rising, as the world gets crazier.
