Earlier this month, I took my 2-year-old son shopping for a Halloween costume. We stooped in the children’s Halloween aisle, raking through the half-opened bags of muscle-bound superheroes, gruesome monsters, colorful hippies and cute, cuddly animals. After a few minutes of rummaging and laughing at how silly we looked in giant sunglasses and crazy wigs, he suddenly stopped and stared at a package hanging on the wall in front of him.
