Maybe the fall of Toys R Us will embolden entrepreneurs to start up new stores that cater to moms and pops who crave a more manageable experience — taking a child to a neighborhood store that doesn’t just pluck boxes from shelves and transport them to the cashier, but lets kids explore and, above all, play. These cozier toy tableaux — many small toy stores already are thriving — could sell more parents on less frenzy and chaos than the typical whining-on-every-aisle model.
