Slatter started the Yellow Pumpkin Parade after an unpleasant experience while taking her 4-year-old son, who has apraxia of speech, trick-or-treating. Uttering his best version of "trick-or-treat" when knocking on doors, Slatter's son was thrilled when the first piece of candy was dropped into his bucket. One woman kept pressing him to properly enunciate "trick-or-treat," but Slatter's son was unable to do this, so he left that proch without a piece of candy. Now, Slatter sees yellow pumpkins as a symbol that can help children have a trick-or-treating experience like every other child while also sparking a discussion about the condition. In addition to launching a marketing campaign to encourage the use of yellow pumpkins on porches, she also raised funds to pass out 1,000 yellow trick-or-treat bags for children with apraxia of speech and other disabilities in South Carolina.
