A Toys R Us in King of Prussia, Pennsylvania, turned off its music for three hours on a recent Saturday morning and turned its break room into a quiet zone as part of an event planned with the Greater Philadelphia Autism Society. The company’s 100 stores in the U.K. have been offering similar hours for one day a year since 2014, and Toys R Us plans to bring similar events to more of its 900 U.S. stores. Chuck E. Cheese’s, the chain with arcade games and rides, similarly plans to turn off the music and dim the lights at 40 Northeast restaurants for a couple of hours one Sunday a month starting in January, as part of a trial run.

In the meantime, small stores designed specifically for children with sensory issues are popping up as well.

“The need for a store like this is even bigger than I thought it would be,” said Bethany Mathis, who opened Time 4 Toys last month after having a hard time finding toys for her 8-year-old son with sensory processing issues. The walls at the store in Flowood, Mississippi, are painted in soft colors, and kids can test out the toys.

An estimated one in 68 children have autism or a related disorder, according to a government study based on 2012 data. That’s up from one in 150 a decade before. Symptoms of autism vary widely, and can range from mild social interaction problems to repetitive behaviors to difficulty speaking or even the inability to speak. This can make choosing toys even harder than it is for unaffected kids.

Jamilah Rahim opened Spectrum Toy Store in Chicago this year after she realized no toy stores were meeting that need. As an in-home behavioral therapist, she saw parents spend money buying toys online their children ended up not being interested in. At her 700-square-foot store, kids can sit and play with any of the toys, and parents can see if they like them before buying.
